title: trans-Bis(2-amino-6-nitro-1,3-benzothiazole-N)dichloroplatinum(II) tetrakis(N,N'-dimethylformamide) solvate and tetrakis(2-amino-5-methyl-1,3,4-thiadiazole-N4)platinum(II) hexachloroplatinate(IV) bis(N,N'-dimethylformamide) solvate.
abstract: The structures of the title compounds, [PtCl(2)(C(7)H(5)N(3)O(2)S)(2)].4C(3)H(7)NO, (I), and [Pt(C(3)H(5)N(3)S)(4)][PtCl(6)].2C(3)H(7)NO, (II), respectively, comprise square-planar Pt(II) centres. In the cation and anion of (II), the Pt atoms lie on independent inversion centres. For (I), the metal atom is N-bonded to two trans organic ligands and also bonded to two Cl atoms, whereas in (II), the Pt atom is N-bonded to four organic ligands, the charge being balanced by the presence of an additional [PtCl(6)](2-) species (from the starting material). Both structures contain dimethylformamide solvate molecules, four in the asymmetric unit of (I) and one in (II), which are involved in the hydrogen-bonding network via N-H.X and C-H.X associations.
