title: Bis[μ-5-(5-carboxyl-ato-3-pyrid-yl)tetra-zolato-κN,N:N]bis-[triaqua-zinc(II)].
abstract: In the title complex, [Zn(2)(C(7)H(3)N(5)O(2))(2)(H(2)O)(6)], the 5-(5-carboxyl-ato-3-pyrid-yl)tetra-zolate ligand chelates the Zn(II) center through one pyridyl N and one tetra-zolate N atom, and uses another N atom to bridge to the second Zn atom, forming a centrosymmetric dinuclear unit. Three coordinated water mol-ecules complete the distorted octa-hedral geometry of the Zn(II) atom. O-H⋯O and O-H⋯N hydrogen bonds involving the coordinated water mol-ecules, tetra-zolate N atoms and the carboxyl-ate group result in a three-dimensional structure.
