Aqua-bis-(4-chloro-benz-yl)bis-(nicotinato-κO,O')tin(IV)

In the title mol-ecule, [Sn(C(7)H(6)Cl)(2)(C(6)H(4)NO(2))(2)(H(2)O)], the O atoms of the two chelating nicotinate groups and the O atom of the coordinated water mol-ecule comprise the penta-gonal plane of the trans-C(2)SnO(5) penta-gonal-bipyramid [C-Sn-C = 178.62 (11) °] surrounding the Sn(IV) atom. In the crystal, adjacent mol-ecules are linked by O-H⋯N hydrogen bonds, generating a chain running along the body diagonal of the triclinic unit cell.
