Abstract (sommario):

Organometallic compounds are defined as containing at least one metal-carbon bond between an organic molecule, ion, or radical and a metal. Organometallic nomenclature therefore usually combines the nomenclature of organic chemisty and that of coordination chemistry. Provisional rules outlining nomenclature for such compounds are found both in Nomenclature of Organic Chemistry, 1979 and in Nomenclature of Inorganic Chemistry, 1990This document describes the nomenclature for organometallic compounds of the transition elements, that is compounds with metal-carbon single bonds, metal-carbon multiple bonds as well as complexes with unsaturated molecules (metal-p-complexes).Organometallic compounds are considered to be produced by addition reactions and so they are named on an addition principle. The name therefore is built around the central metal atom name. Organic ligand names are derived according to the rules of organic chemistry with appropriate endings to indicate the different bonding modes. To designate the points of attachment of ligands in more complicated structures, the h, k, and m-notations are used. The final section deals with the abbreviated nomenclature for metallocenes and their derivatives.ContentsIntroduction Systems of Nomenclature2.1 Binary type nomenclature 2.2 Substitutive nomenlcature 2.3 Coordination nomenclature Coordination Nomenclature3.1 General definitions of coordination chemistry 3.2 Oxidation numbers and net charges 3.3 Formulae and names for coordination compounds Nomenclature for Organometallic Compounds of Transition Metals 4.1 Valence-electron-numbers and the 18-valence-electron-rule 4.2 Ligand names 4.2.1 Ligands coordinating by one metal-carbon single bond 4.2.2 Ligands coordinating by several metal-carbon single bonds 4.2.3 Ligands coordinating by metal-carbon multiple bonds 4.2.4 Complexes with unsaturated molecules or groups 4.3 Metallocene nomenclature

Abstract (sommario):

In mammals like humans, adult fitness is improved due to resource allocation, investing energy in the developmental growth process during the juvenile period, and in reproduction at the adult stage. Therefore, the attainment of their target body height/size co-occurs with the acquisition of maturation, implying a need for coordination between mechanisms that regulate organismal growth and maturation timing. Insects like Drosophila melanogaster also define their adult body size by the end of the juvenile larval period. Recent studies in the fly have shown evolutionary conservation of the regulatory pathways controlling growth and maturation, suggesting the existence of common coordinator mechanisms between them. In this review, we will present an overview of the significant advancements in the coordination mechanisms ensuring developmental robustness in Drosophila. We will include (i) the characterization of feedback mechanisms between maturation and growth hormones, (ii) the recognition of a relaxin-like peptide Dilp8 as a central processor coordinating juvenile regeneration and time of maturation, and (iii) the identification of a novel coordinator mechanism involving the AstA/KISS system.

Abstract (sommario):

The metal ion coordination abilities of reduced and oxidized glutathione are reviewed. Reduced glutathione (GSH) is a very versatile ligand, forming stable complexes with both hard and soft metal ions. Several general binding modes of GSH are described. Soft metal ions coordinate exclusively or primarily through thiol sulfur. Hard ones prefer the amino acid-like moiety of the glutamic acid residue. Several transition metal ions can additionally coordinate to the peptide nitrogen of the gamma-Glu-Cys bond. Oxidized glutathione lacks the thiol function. Nevertheless, it proves to be a surprisingly efficient ligand for a range of metal ions, coordinating them primarily through the donors of the glutamic acid residue.

Abstract (sommario):

Metals play vital roles in both the mechanism and architecture of biological macromolecules, and are the most frequently encountered ligands (i.e. non-solvent heterogeneous chemical atoms) in the determination of macromolecular crystal structures. However, metal coordinating environments in protein structures are not always easy to check in routine validation procedures, resulting in an abundance of misidentified and/or suboptimally modeled metal ions in the Protein Data Bank (PDB). We present a solution to identify these problems in three distinct yet related aspects: (1) coordination chemistry; (2) agreement of experimental B-factors and occupancy; and (3) the composition and motif of the metal binding environment. Due to additional strain introduced by macromolecular backbones, the patterns of coordination of metal binding sites in metal-containing macromolecules are more complex and diverse than those found in inorganic or organometallic chemistry. These complications make a comprehensive library of "permitted" coordination chemistry in protein structures less feasible, and the usage of global parameters such as the bond valence method more practical, in the determination and validation of metal binding environments. Although they are relatively infrequent, there are also cases where the experimental B-factor or occupancy of a metal ion suggests careful examination. We have developed a web-based tool called CheckMyMetal [1](http://csgid.org/csgid/metal_sites/) for the quick validation of metal binding sites. Moreover, the acquired knowledge of the composition and spatial arrangement (motif) of the coordinating atoms around the metal ion may also help in the modeling of metal binding sites in macromolecular structures. All of the studies described herein were performed using the NEIGHBORHOOD SQL database [2], which connects information about all modeled non-solvent heterogeneous chemical motifs in PDB structure by vectors describing all contacts to neighboring residues and atoms. NEIGHBORHOOD has broad applications for the validation and data mining of ligand binding environments in the PDB.

Abstract (sommario):

The chemistry of NHC core pincer ligands of LX2 type bearing two pending arms, identical or not, whose coordinating center is anionic in nature, is here reviewed. In this family, the negative charge of the coordinating atoms can be brought either by a carbon atom via a phosphonium ylide (R3P+–CR2−) or by a heteroatom through amide (R2N−), oxide (RO−), or thio(seleno)oxide (RS−, RSe−) donor functionalities. Through selected examples, the synthetic methods, coordination properties, and applications of such tridentate systems are described. Particular emphasis is placed on the role of the donor ends in the chemical behavior of these species.

Abstract (sommario):

There is much agreement among chemical education researchers that expertise in chemistry depends in part on the ability to coordinate understanding of phenomena on three levels: macroscopic (observable), sub-microscopic (atoms, molecules, and ions) and symbolic (chemical equations, graphs, etc.). We hypothesize this “level-coordination ability” is related to the formation and use of principle-based, vs. context-bound, internal representations or schemas. Here we describe the development, initial validation, and use of a card sort task to measure the level-coordinating ability of individuals with varying degrees of preparation in chemistry. We have also developed a novel method for generating two-dimensional sorting coordinates which were used to arrange participants along a hypothetical progression of level-coordination ability. Our findings suggest the card sort task shows promise as a tool to assess level-coordination ability. With the exception of graduate students, participant groups on average progressed from sorting by level of representation toward sorting by underlying principle. Graduate students unexpectedly sorted primarily by level of representation. We use these data to form initial hypotheses about a typical process for the development of level-coordination ability and schema formation. In doing so, we demonstrate the usefulness of our task paired with sorting coordinate analysis as a tool to explore the space between novice and expert behavior. Finally, we suggest potential uses for the task as a formative assessment tool at the classroom and program levels.
