Different inter­molecular inter­actions in azido­[2-(diphenyl­phosphino)­benzaldehyde semicarbazonato-κ2P,N1,O]nickel(II)

Abstract

The title compound, [Ni(C20H17N3OP)(N3)], is the first complex with a semicarbazide-based ligand having a P atom as one of the donors. The influence of the P atom on the deformation of the coordination geometry of the Ni II ion is evident but less expressed than in the cases of complexes with analogous seleno- and thio-semicarbazide ligands. The torsion angles involving the two bonds formed by the P atom within the six-membered chelate ring have the largest values [C - P - Ni - N = 24.3 (2)° and C - C - P - Ni = -24.2 (4)°], suggesting that the P atom considerably influences the conformation of the ring. Two types of N - H⋯N hydrogen bond connect the complex units into chains. © 2009 International Union of Crystallography.
