چکیده
The title compound, [Zn(C(14)H(8)N(2)O(4))(H(2)O)(2)](n), consists of zigzag chains of Zn atoms bridged by azobenzene-4,4'-dicarboxyl-ate ligands. The Zn(II) atom, lying on a twofold rotation axis, is coordinated by four O atoms from the carboxyl-ate groups and two water mol-ecules, giving rise to a considerably distorted octa-hedral coordination envionment. The ligand lies on an inversion center. In the crystal structure, π-π inter-actions between the ligands [inter-planar distance = 3.527 (3) Å] assemble the chains into a sheet-like structure. O-H⋯O hydrogen bonds between the coordinated water mol-ecules and carboxyl-ate O atoms connect the sheets into a three-dimensional network.
