catena-Poly[[bis(4-cyanobenzoato-O)copper(II)]-di--3-aminopyridine-²N¹:N³;²N³:N¹]

H.-Y. He and L.-G. Zhu

Abstract: In the title complex, [Cu(C₈H₄NO₂)₂(C₅H₆N₂)₂]_n, the two crystallographically distinct Cu atoms each lie on an inversion centre and are coordinated by N atoms from four 3-aminopyridine ligands, two from the amino groups and two from the pyridine rings. The octahedral coordination about each Cu atom is completed by two carboxylate O atoms from different 4-cyanobenzoate ligands. The 3-aminopyridines serve as bridging ligands, linking adjacent Cu atoms into one-dimensional chains. In the crystal structure, weak N-HO hydrogen-bonding interactions form a two-dimensional layer structure.
