A Z-type PGeP pincer germylene ligand in a T-shaped palladium(0) complex

Abstract

A dipyrromethane-based germylene decorated with two phosphane groups has been used to prepare an unusual T-shaped palladium(0) containing a PGeP pincer germylene that acts as a Z-type ligand. This compound is a strong reducing reagent, as it has been easily oxidized to germyl–palladium(II) derivatives with a gold(I) complex, HCl and Ph₂S₂ through processes that involve formal addition of a bond of the oxidant across the Ge–Pd bond.
