Synthesis, crystal structure and Hirshfeld surface analysis of di-μ2-chlorido-bis-[(nitrato-κ O )bis-(pyridine-κ N )copper(II)].

Abstract

The title compound, [Cu2Cl2(NO3)2(C5H5N)4], crystallizes as a centrosymmetric binuclear CuII complex in which the two central CuII atoms are inter-connected by a pair of μ2-chlorido bridges. The CuII atom is additionally coordinated by two pyridine N atoms and one O atom from a monodentate nitrato ligand, resulting in a distorted square-pyramidal coordination environment. In the crystal, the binuclear complexes are linked by C-H⋯Cl and C-H⋯O hydrogen bonds, generating a supra-molecular framework structure. Hirshfeld surface analysis was performed to qu-antify and further elucidate the inter-molecular inter-actions.
