Group II metal complexes of the germylidendiide dianion radical and germylidenide anion
The two-electron reduction of a Group 14-element(I) complex [RË⋅] (E=Ge, R=supporting ligand) to form a novel low-valent dianion radical with the composition [RË:]. 2− is reported. The reaction of [LGeCl] (1, L=2,6-(CH[DOUBLE ...
A base-stabilized lead(I) dimer and an aromatic plumbylidenide anion
The aromatic low-valent lead analogue of an indenyl anion (see scheme; 1) undergoes oxidation with SnCl2 to form the base-stabilized lead(I) dimer 2. Reduction of 2 with lithium regenerates 1. These compounds were characterized ...
Heteroleptic Germanium(II) and Tin(II) chlorides supported by anionic ligands derived from 2,3-dimethyl-1,4-diaza-1,3-butadiene
The syntheses and structures of heteroleptic germanium(II) and tin(II) chlorides supported by anionic ligands derived from 2,3-dimethyl-1,4-diaza-1,3-butadiene are described. The reaction of ArN=C(Me)C(Me)=NAr (L, Ar = ...
