A Germanium(II)-Centered Dication

Abstract

The dicationic 4 2+ complex with three N-heterocyclic carbenes coordinated to a germanium center is reported. The complex was characterized by 1 H NMR and FT Raman spectroscopy, and the structure was determined by single-crystal X-ray diffraction. Electronic structure calculations reveal a partial positive charge at germanium and that the germanium lone pair shows no evidence for π bonding.
