title: μ-Oxalato-κO,O:O,O-bis-[diaqua-(2,2'-bipyridyl-κN,N')zinc] bis-[2-(1H-benzotriazol-1-yl)acetate] hexa-hydrate.
abstract: The asymmetric unit of the title compound, [Zn(2)(C(2)O(4))(C(10)H(8)N(2))(2)(H(2)O)(4)](C(8)H(6)N(3)O(2))(2)·6H(2)O, contains one half of the centrosymmetric binuclear cation, one anion and three water mol-ecules. In the cation, the oxalate ligand bridges two Zn(II) ions in a bis-bidentate fashion, so each Zn(II) ion is coordinated by two O atoms from the oxalate ligand, two N atoms from two 2,2'-bipyridine ligands and two water mol-ecules in a distorted octa-hedral arrangement. The mean planes of the oxalate and 2,2'-bipyridine ligands form a dihedral angle of 80.0 (1)°. An extensive three-dimensional hydrogen-bonding network formed by classical O-H⋯O and O-H⋯N inter-actions consolidates the crystal packing.
