چکیده
The structure of the title compound, [Zn(C14H18N4)(C2H3N)(H2O)](ClO4)2, contains a six-coordinate cation consisting of the tetra-dentate bis-picen ligand, coordinated water, and coordinated aceto-nitrile, 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 bis-picen 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.

In the title complex, [Cu(ClO(4))(2)(C(7)H(12)N(2)O)(2)], the Cu(II) ion lies on a crystallographic inversion centre. The coordination sphere around Cu(II) ion can be described as tetragonally distorted octa-hedral with two perchlorate O atoms occupying the apical positions and four N atoms from two N(1)-(2-furyl-methyl)ethane-1,2-diamine ligands in the basal plane.
