title: cis-Diaqua-bis(2,2',2''-tripyridylamine)zinc(II) bis-(perchlorate).
abstract: In the title compound, [Zn(2,2',2''-tpa)(2)(H(2)O)(2)](ClO(4))(2) (2,2',2''-tpa is 2,2',2''-tripyridylamine, C(15)H(12)N(4)), the Zn center lies on a twofold axis and is coordinated octa-hedrally by two water mol-ecules and two bidentate 2,2',2''-tpa ligands. The perchlorate anions are linked to the coordinated water mol-ecules in the complex cations via O-H⋯O hydrogen bonds.
