摘要：
The crystal and molecular structure of the title compound, [Pd(S = C(NH2)2)4]Cl2.2dmtp.2H2O, has been determined and refined to a final R = 0.034. The cation is centrosymmetric with the Pd atom existing in a square planar geometry with two disparate Pd-S bond distances of 2.3129(9) and 2.292(1) angstrom. Interatomic parameters are reported for the first non-coordinated dmtp molecule; these suggest the predominance of a particular canonical form in the solid state. The lattice is stabilized via a series H-bonding contacts involving the thiourea, Cl- and dmtp species. Crystals of [Pd(S = C(NH2)2)4]Cl2.2dmtp.2H2O are monoclinic with space group P2(1)/c, and unit cell dimensions a = 15.129(1), b = 8.512(1), c = 12.663(1) angstrom, beta = 104.05(1)-degrees.
