Crystal structure of bromidonitrosylbis(triphenylphosphane-κP)nickel(II)

Abstract

The asymmetric unit of the title complex, [NiBr(NO){P(C6H5)3}2], comprises two independent molecules each with a similar configuration. The NiII cation is coordinated by one bromide anion, one nitrosyl anion and two triphenylphosphane molecules in a distorted BrNP2 tetrahedral coordination geometry. The coordination of the nitrosyl group is non-linear, the Ni—N—O angles being 150.2 (5) and 151.2 (5)° in the two independent molecules. In the crystal, molecules are linked by weak C—H...Br hydrogen bonds and weak C—H...π interactions into a three-dimensional supramolecular architecture.
