  Mitigating repulsions in close quarters: Copper tells us how!

  摘要：

  Four copper(l) complexes of short bite ligands, bis(diphenylphosphino)amine (dppa) and bis(diphenylphosphino)isopropylamine (dppipa) were synthesized from appropriate precursors. All complexes were characterized by single crystal X-ray crystallography and spectroscopic techniques. In each of these complexes, two filled shell cations are forced into close proximity (approximate to 2.7-2.8 angstrom). With no strong pi acid ligands to siphon electron density from the filled d shell, the unavoidable repulsive d(10)-d(10) interaction is mitigated when an unsymmetrical coordination environment around the copper atoms exists. The coordinatively saturated copper ion functions as a donor to the coordinatively unsaturated copper. A Cambridge Structural Database (CSD) search reveals the greater propensity of clusters with short contacts to adopt unsymmetrical coordination. (c) 2006 Elsevier Ltd. All rights reserved.
