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—H⋯O hydrogen-bonding inter­actions form a two-dimensional layer structure.
