V[double bond, length as m-dash]O⋯C interactions in crystal structures of oxovanadium-coordination compounds

Abstract

A survey of the Cambridge Structural Database (CSD) revealed the existence of a new supramolecular homosynthon in oxovanadium coordination compounds (OCCs) that is based on non-covalent V[double bond, length as m-dash]O⋯C interactions. V[double bond, length as m-dash]O⋯C close contacts were found in 38.7% of structures containing vanadyl or pervanadyl groups. The V[double bond, length as m-dash]O⋯C interaction is clearly distinguishable from a putative V[double bond, length as m-dash]O⋯H–C hydrogen bond upon analysis of OCC crystal structures deposited in the CSD. In the majority of structures, the OCCs assemble to form dimers or polymers. The V[double bond, length as m-dash]O⋯C interactions were also found to lead to self-assembly of two new oxovanadium β-diketonate complexes into dimers in the solid state.
