| Abstract | Platinum phosphine complexes with bridging sulfide ligands catalyze reductive desulfurization under mild conditions and serve as model hydrodesulfurization catalysts [1]. In this regard, water-soluble sulfide-bridged platinum complexes are of interest in terms of their applicability for the development of environmentally friendly catalytic processes. Phosphine ligands containing hydroxyalkyl groups such as tris(hydroxymethyl)phosphine (P(CH2OH)3, THP) and its analogues form stable water-soluble complexes with the Pd, Pt, Rh, Re, Ru, Ir, Mo [2-7]. We have previously described the first water-soluble platinum sulfide complex THP, [Pt3S2(P(CH2OH)3)6]Cl2 [8]. In this work we report the crystal structure of a new water-soluble complex [Pt3S2(P(CH2OH)3)6](PF6)(OH)⋅H2O. Experimental. [Pt3S2(P(CH2OH)3)6](PF6)(OH)⋅H2O (1) was obtained by mixing the solutions of 114 mg (0.08 mmol) of [Pt3S2(P(CH2OH)3)6]Cl2 [8] in 10 ml CH3OH and 0.152 mg (0.93 mmol) of NH4PF6 in 5 ml H2O with subsequent slow evaporation in air. After 12 days colorless needle-shaped single crystals of [Pt3S2(P(CH2OH)3)6](PF6)(OH)⋅H2O separated. Yield 0.082 g (67%). Analysis. Calculated (%): C 13.74, H 3.65, S 4.07. Found (%): C 13.70, H 3.62, S 4.02. X-ray diffraction analysis was carried out in a routine way on an automated four-cycle Bruker-Nonius X8 Apex diffractometer equipped with a two-coordinate CCD-detector using Mo anode emission (λ = 0.71073 Å) and a graphite monochromator. The intensities of the reflections were measured at T = 150 K by φ and ω scanning of narrow (0.5°) frames. Absorption was applied empirically with the SADABS [9] program. The structure was solved by direct methods and refined with the full-matrix least square method |F 2| in the anisotropic approximation for non-hydrogen atoms using the SHELXTL program package [10]. The THP hydrogen atoms were placed in geometrically calculated positions and refined in the rigid body approximation. The CIF file containing complete structural information has been deposited with the Cambridge Structural Database [11] under depository number CCDC 883606 and can be obtained from the authors upon request. |
