Abstract

In the title complex, {[Cu(C11H16N4)2(H2O)2](C10H6O6S2)}n, the CuII atom, lying on an inversion center, is six-coordinated by two water molecules and four N atoms from four 1,5-bis(1H-imidazol-1-yl)pentane (biim-5) ligands in a distorted octahedral geometry. Adjacent CuII atoms are linked by two biim-5 ligands, forming a chain along [111]. Two atoms of the pentane group are disordered over two sets of sites, with an occupancy ratio of 0.554 (18):0.446 (18). Intermolecular O—H...O hydrogen bonds link the chains and the centrosymmetric naphthalene-1,5-disulfonate anions into a layer structure parallel to (0-11).
