✦ Synopsis
The mono-and bidentate chelation of the main-group related bis(diamino)-and the higher element homologue bis(diarsanyl)methanide ligand systems have been studied. elements silicon, germanium, tin, and lead through the phosphorus atoms of the diphosphanylmethanide ligand has
The bonding situation in the hitherto experimentally unknown bis(diamino)methanide ligands is predicted to be been studied by means of quantum chemical methods. In accord with experimental investigations, the species are similar to that in bis(amidinate) complexes. An analysis of the electron distributions (natural bond orbital population found to adopt a ψ-tbp conformation of high flexibility. The various distortional modes causing the axial and equatorial analysis) in these compounds reveals that the central maingroup element is positively charged and weakly chelated by positions to become equivalent have also been investigated. In addition, the bonding situations in the electronically the surrounding ligands.
