Mason et al. have proposed that metal-metal bonding on the periphery of gold clusters is unimponant and that only radial bonding needs to be considered for structural predictions [14]. In this view, the central atom of the cluster often adopts an electron configuration with the peripheral metal atoms acting as ligands. Silicon, Germanium, Tin and Lead-- 1 Overview-- 2 Multiple Bonds in Group 3 Tetrylenes-- 4 Radicals, Cations and Anions-- 5 Homoaromatics and Other Ring Systems-- 6 Pi-Bonded Complexes-- 7 Group 14 Organometallics as Ligands at Transition Metal Centres-- References-- Recent Advances in the Chemistry of Phosphaalkynes: Building Blocks. An overview is presented of the key role for heavy-metal compounds in medicine with a focus on DNA binding, and on Pt compounds used in treatment of cancer. Molecular aspects of the mechanism of action are reviewed in more detail and the consequences of structural distortions will be by: 3.

DEE, T. Structural Studies on Some Bivalent Metal Complexes Abstract Previous investigations of the solid-state structures of (R^P)2 ^ X 2 and (R3P)HgX2 complexes have been extended by the determination of the following crystal structures. A homonuclear molecule is a diatomic molecule consisting of 2 molecules with the same nuclei (H2, O2, etc) these molecules are nonpolar, covalents and have inversion symmetry.

A heteronuclear molecules is a diatomic moleculein with the 2 nuclei are. In all cases the energy differences are found to be within the accuracy of the calculations. The Cr compounds have a metal-metal bond order of 2.
