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

A new mononuclear Ni(II) complex with bis-(pyridin-2-yl)amine (dpyam) and benzoate (benz), [Ni(C(7)H(5)O(2))(2)(C(10)H(9)N(3))], crystallizes in the monoclinic space group P2(1)/c. The Ni(II) ion adopts a cis-distorted octa-hedral geometry with an [NiN(2)O(4)] chromophore. In the crystal, the complex mol-ecules are linked together into a one-dimensional chain by symmetry-related π-π stacking inter-actions [centroid-to-centroid distance = 3.7257†(17)†à ], along with N-H⋯O and C-H⋯O hydrogen bonds. The crystal packing is further stabilized by C-H⋯π inter-actions, which were investigated by Hirshfeld surface analysis.
