| Popis: | The crystal structure of tris(triphenylphosphine)gold(I)[dodecahydrido-6-thia-nido-decaborate(1—)], [(C6H5)3P]3AuB9H12S, has been determined using X-ray techniques and counter data. The compound is a salt consisting of [(C6H5)3P]3Au+ cations and B9H12S− anions. The cation is trigonal and nearly planar with AuP distances of 2.382(5) A and PAuP angles of 119.3(36)°. The B9H12S− thiaborane anion is an open icosahedral fragment with the S atom in the 6 position, on the periphery of the decaborane polyhedron. The structure is the same as that found in solution for the isoelectronic B10H142− anion. Crystals are triclinic, space group P 1 , with a = 13.086(12), b = 19.635(32), c = 11.180(8) A, α = 103.60(16), β = 72.10(9), and γ = 94.76(15)°. The structure was refined by least squares to a conventional R of 0.077. |
