Bis(diphenylphosphino)methane and related ligands as hydrogen bond donors†

Abstract

A search of the Cambridge Structural Database reveals that the methylene group of coordinated bis(diphenylphosphino)methane and related ligands can act as a hydrogen bond donor, with H···O distances as short as 2.20 Å; analogous C–H···Cl^– interactions are a feature of the packing of dppmSe complexes of silver(I) and gold(I).
