title: trans-Bis(5-amino-1,3,4-thia-diazol-2-thio-lato-κS(2))bis-(triphenyl-phosphane-κP)palladium(II) dimethyl sulfoxide disolvate hemihydrate.
abstract: The title complex, [Pd(C(2)H(2)N(3)S(2))(2)(C(18)H(15)P)(2)]·2C(2)H(6)OS·0.5H(2)O, was obtained from the reaction of trans-[(Ph(3)P)(2)PdCl(2)] with 5-amino-1,3,4-thia-diazole-2-thione (SSNH(2)) in a 2:1 molar ratio. The Pd(II) atom, located in a crystallographic center of symmetry, has a square-planar geometry with two triphenyl-phosphine P-coordinated mol-ecules and two SSNH(2) ligands with the S atoms in a trans conformation. The latter ligand exhibits N-H⋯N hydrogen-bonding contacts formed by the amino group with the thia-diazole ring, generating a chain along the c axis. The asymmetric unit contains one half of the complex mol-ecule along with disordered dimethyl sulfoxide and water mol-ecules.
