Synthesis, crystal structure and Hirshfeld surface analysis of a coordination compound of cadmium nitrate with 2-amino-benzoxazole.

A coordination complex of cadmium nitrate [Cd(NO)] with 2-amino-benzaxole (2AB; CHNO), namely, tetra-kis-(2-amino-benzoxazole-κ )bis-(nitrato-κ)cadmium(II), [Cd(NO)(2AB)], has been synthesized from ethanol solutions of Cd(NO)·HO and 2AB. The asymmetric unit comprises half a mol-ecule of [Cd(NO)(2AB)], with the Cd atom positioned on a twofold rotation axis. In the completed mol-ecular complex, four 2AB ligands and two nitrate anions each coordinate monodentately to the Cd atom, leading to a distorted octa-hedral coordination environment. The crystal structure of [Cd(NO)(2AB)] exhibits several N-H⋯O inter-actions, resulting in the formation of a layered assembly parallel to (001). Hishfeld surface analysis was used to qu-antify the inter-molecular inter-actions.
