title: Bis(2,2'-diamino-4,4'-bi-1,3-thia-zole-κN,N)bis-(nitrato-κO)lead(II) dihydrate.
abstract: In the title compound, [Pb(NO(3))(2)(C(6)H(6)N(4)S(2))(2)]·2H(2)O, the Pb(II) cation is N,N'-chelated by two 2,2'-diamino-4,4'-bi-1,3-thia-zole (DABT) ligands and further is cis coordinated by two nitrate anions in a distorted PbN(4)O(2) octa-hedral geometry. One of the uncoordinated water mol-ecules is close to an inversion center and is disordered equally over two sites. Intra-molecular N-H⋯N and N-H⋯O inter-actions are present. An extensive hydrogen-bonding network of types N-H⋯O, O-H⋯O, O-H⋯N and O-H⋯S consolidates the crystal structure.
