The reactions of triphenylgermane and triphenyltin hydride with coordinatively saturated organozinc or organocadmium compounds give organometallic complexes containing Group IV (Ge, Sn)-Group II(Zn, Cd) metalmetal bonds. The 2,2′-bipyridine complexes show solvent-dependent charge-transfer absorptions in the visible region. The occurrence of charge transfer may account for the observation that the

Triphenyltin-zinc compounds are easily accessible by means of hydrostannolysis reactions of zinccarbon bonds in coordinatively saturated organozinc compounds. The chemical behaviour of (triphenyltin)zinc chloride was found to depend greatly on the coordination state of the zinc atom. In the absence of strongly coordinating ligands, 1,2-intermetallic migration of a phenyl group from tin to zinc occurs
