Abstract
[Pt3S2(P(CH2OH)3)6](PF6)(OH)×H2O (1) is obtained by a reaction of [Pt3S2(P(CH2OH)3)6]Cl2 with NH4PF6. The crystal structure of 1 was determined by a single crystal X-ray diffraction analysis (space group R3c a = 12.0042(2) Å, c = 52.6879(11) Å, V = 6575.2(2), Z = 6, C18H57F6O20P7Pt3S2, dx = 2.385 g/cm3, T = 150 K, R1 = 0.044 for 2123 F0 > 4δ(F) until 2θmax = 63°). The cations contain a {Pt3(μ3-S)2}2+ core with nonbonding Pt…Pt distances of 3.1536(6) Å. The Pt atoms are in a square planar environment; the Pt–S and Pt–P bond lengths are 2.3586(16) Å and 2.260(2) Å respectively.
