metal-organic compounds
The monoclinic form of the title compound, [Cu(C7H5O3)2(C6H6N2O)2], was isolated during the systematic synthesis of copper salicylates. A distorted octahedral coordination around CuII, located on the centre of symmetry, is formed by four carboxylic O atoms from two salicylate ligands [Cu—O 1.928 (2) and 2.766 (2) Å] and by two N atoms from two nicotinamide groups [Cu—N 2.022 (2) Å]. Monomeric structural units are linked together via hydrogen bonds of the type N—H
O between the N and O atoms of the nicotinamide ligands.
