Crystal structure and Hirshfeld surface analysis of bis(benzoato-κ2O,O′)[bis(pyridin-2-yl-κN)amine]nickel(II)

Abstract

A new mononuclear NiII complex with bis(pyridin-2-yl)amine (dpyam) and benzoate (benz), [Ni(C7H5O2)2(C10H9N3)], crystallizes in the monoclinic space group P21/c. The NiII ion adopts a cis-distorted octahedral geometry with an [NiN2O4] chromophore. In the crystal, the complex molecules are linked together into a one-dimensional chain by symmetry-related π–π stacking interactions [centroid-to-centroid distance = 3.7257 (17) Å], along with N—H...O and C—H...O hydrogen bonds. The crystal packing is further stabilized by C—H...π interactions, which were investigated by Hirshfeld surface analysis.
