Controlled Growth of Dichlorogermanium Oligomers from Lewis Basic Hosts

Abstract

To branch or not to branch: A mild stepwise route to various linear and branched (GeCl2)x oligogermylenes supported by Lewis bases is reported, including the carbene-bound Ge4 complex NHC⋅GeCl2Ge(GeCl3)2 (see picture). Dipp=2,6-iPr2C6H3, NHC=N-heterocyclic carbene.
