Isomers in the Chemistry of Germanium Heterometallic Clusters
نویسندگان
چکیده
Sixteen isomers of heterometallic germanium clusters have been analysed in this review. There are two types of isomerism, distortion (x 15) and cis – trans (x 1) and cis – isomer contains two crystallographically independent molecules. Distortion isomers, differing only by degree of distortion in Ge – L, Ge – M (M = metal) distances and L – Ge L (L = ligand) angles. The data are discussed with these found in the isomerism of germanium coordination compounds as well as organogermanium derivatives. In the chemistry of germanium were found-seventy four derivatives as isomers. These are discussed and compared with those in tin (over two hundred and fifty examples) and lead (seventy examples) chemistry. This review and its precursors give the first overall survey of the structural data for the isomer complexes of the group IV metals.

Isomers in the Chemistry of Germanium Coordination Compounds
The coordination chemistry of germanium covers quite bulk fields, as shown by a survey covering the crystallographic and structural data of over two hundred examples. About ten percent of those complexes exist as distortion isomers and are summarised. These are discussed in terms of the coordination around the germanium(I), germanium(II) and germanium(IV) atoms, and correlations are drawn betwe...
متن کاملIsomerism in the Chemistry of Organogermanium Compounds (Part II)
The organogermanium chemistry covers huge fields, as shown by a survey covering the crystallographic and structural data of over four hundred and fifty examples. Over 10 percent of those compounds exist as distortion isomers (around 97 %) and ligand isomers (around 3 %). These are discussed in term of coordination around the Ge(II), Ge(IV) and Ge2 +3 atoms, and correlations are drawn between do...

Carbon oxide gaseous species are potentially considered as pollutants of the atmosphere of earth; especially, carbon monoxide and carbon dioxide which are of the well-known carbon oxids, play an effective role in the greenhouse gas emissions. Moreover, these species could initiate or handle some chain reactions in the troposphere that lead to emergence of some secondly air pollutants which may ...

متن کاملProbing the structural evolution of ruthenium doped germanium clusters: Photoelectron spectroscopy and density functional theory calculations
We present a combined experimental and theoretical study of ruthenium doped germanium clusters, RuGen(-) (n = 3-12), and their corresponding neutral species. Photoelectron spectra of RuGen(-) clusters are measured at 266 nm. The vertical detachment energies (VDEs) and adiabatic detachment energies (ADEs) are obtained. Unbiased CALYPSO structure searches confirm the low-lying structures of anion...
