Abstract

In the title octahedral complex, [Cu{N(CN)2}2(ampym)2]n (ampym is 4-amino­pyrimidine, C4H5N3), the Cu atom is located on an inversion centre and is coordinated in the equatorial plane by two dicyan­amide nitrile N atoms and two N atoms from ampym ligands [Cu—N = 1.972 (2) and 2.001 (2) Å, respectively], and in the axial positions by another two dicyan­amide nitrile N atoms, at 2.633 (2) Å. Neighbouring Cu atoms are connected via double dicyan­amide bridges to form a one-dimensional infinite chain.
