title: Bis(1H-benzotriazole-7-sulfonato-κO)bis-(1,10-phenanthroline-κN,N')cadmium dihydrate.
abstract: In the title complex, [Cd(C(6)H(4)N(3)O(3)S)(2)(C(12)H(8)N(2))(2)]·2H(2)O, the Cd(2+) cation is located on an inversion center and is coordinated by four N atoms from two symmetry-related 1,10-phenanthroline ligands and two sulfonate O atoms from two benzotriazole-7-sulfonate anions, displaying a distorted CdN(4)O(2) octa-hedral geometry. In the crystal, O-H⋯N, O-H⋯O, N-H⋯O, C-H⋯N and C-H⋯O hydrogen bonds occur. The lattice water mol-ecules and sulfonate O atoms as donor or acceptor atoms play important roles in the formation of these inter-actions.
