A novel complex with the stoichiometry [(NH 2) 2 CSSC(NH 2) 2 ] 2 [Os IV Cl 6 ]Cl 2  3H 2 O (1) ... more A novel complex with the stoichiometry [(NH 2) 2 CSSC(NH 2) 2 ] 2 [Os IV Cl 6 ]Cl 2  3H 2 O (1) is isolated as a product of the reaction of H 2 [OsCl 6 ] with thiourea in concentrated НCl under deliberately optimized conditions favoring a partial thiourea oxidation to ,'-dithiobisformamidinium dication but preserving hexachloroosmate [OsCl 6 ] 2anions. A bromide analogue [(NH 2) 2 CSSC(NH 2) 2 ] 2 [Os IV Br 6 ]Br 2  3H 2 O 2 is afforded by a similar reaction. A counter synthesis of 1 is accomplished via the direct ion-exchange reaction between H 2 [OsCl 6 ] and [S 2 C 2 (NH 2) 4 ]Сl 2. Crystal structures of 1 and 2 are unambiguously established by synchrotron radiation-based single-crystal Xray diffraction at 100 K. The two compounds are isostructural and are crystallized in the orthorhombic space group Cmcm, Z = 4. Unit cell parameters are for 1: a = 11.279(2) Å, b = 13.611(3) Å, c = 16.731(3) Å; for 2: a = 11.695(2) Å, b = 14.005(3) Å, c = 17.015(3) Å. The osmium atoms in [OsХ 6 ] 2-(X=Cl or Br) anions adopt slightly distorted octahedral coordination. The ,'dithiobisformamidinium cations are paired into rings via the NН…Сlhydrogen bonds. The rings are further linked into a spatial network by H-bonds with water molecules and S…Cl nonvalence interactions.

The complex 1 crystallized in the orthorhombic space group Pca2 1. For 2, two orthorhombic polymorphs are found, namely, 2 a in space group Cmcm and 2 b in space group Pbca. Within the [H(dmso) 2 ] + cations of 1 and 2 a, the cis-configuration of the DMSO moieties has been observed for the first time. The complexes are characterized by a set of spectroscopic (NMR, IR, UV-Vis, EXAFS/XANES) and diffraction (single crystal and powder) techniques. Both complexes 1 and 2 retain their molecular structures in DMSO and acetone solutions, as evidenced by Os L 3-edge EXAFS/XANES. 1 H NMR spectra of 1 and 2 in DMSO solutions reveal signals of coordinated DMSO. In acetone solutions, signals of the [H(dmso) 2 ] + cations are observed in addition to those of coordinated neutral DMSO.
