A diamino-substituted carbodiphosphorane as strong C-donor and weak N-donor: Isolation of monomeric trigonal-planar L·ZnCl2

Abstract

The isolation, structural characterization and coordination chemistry of a di(amino)-substituted carbodiphosphorane (CDP) are reported. Compared to the analogue, dianionic bis(iminophosphoryl)methandiides, the CDP is a stronger C-, but much weaker N-donor which led to the isolation of solely C-coordinated metal complexes amongst an unusual monomeric trigonal-planar L·ZnCl2 complex.
