【 摘 要 】

The structure of the title compound, [Zn(C14H18N4)(C2H3N)(H2O)](ClO4)2, contains a six-coordinate cation consisting of the tetra­dentate bis­picen ligand, coordinated water, and coordinated aceto­nitrile, with the latter two ligands adopting a cis configuration. There are two formula units in the asymmetric unit. Both cations show almost identical structural features with the bis­picen ligand adopting the more common cis-β conformation. One of the four perchlorate anions is disordered over two positions, with occupancies of 0.9090 (15) and 0.0910 (15). There is extensive inter-ionic hydrogen bonding between the perchlorate anions and O—H and N—H groups in the cations, including a bifurcated hydrogen bond between an N—H group and two O atoms of one perchlorate anion. As a result of this extended hydrogen-bond network, the ions are linked into a complex three-dimensional array.
