Annotatsiya

A coordination complex of cadmium nitrate [Cd(NO 3 ) 2 ] with 2-aminobenzaxole (2AB; C 7 H 6 N 2 O), namely, tetrakis(2-aminobenzoxazole-κ N 1 )bis(nitrato-κ O )cadmium(II), [Cd(NO 3 ) 2 (2AB) 4 ], has been synthesized from ethanol solutions of Cd(NO 3 ) 2 ·H 2 O and 2AB. The asymmetric unit comprises half a molecule of [Cd(NO 3 ) 2 (2AB) 4 ], with the Cd II atom positioned on a twofold rotation axis. In the completed molecular complex, four 2AB ligands and two nitrate anions each coordinate monodentately to the Cd II atom, leading to a distorted octahedral coordination environment. The crystal structure of [Cd(NO 3 ) 2 (2AB) 4 ] exhibits several N—H...O interactions, resulting in the formation of a layered assembly parallel to (001). Hishfeld surface analysis was used to quantify the intermolecular interactions.
