Polysulfanido Ligands - The Preparation and Structures of Complexes of the Type CpRu(Pph(3))(Co)S(X)R, Possessing Disulfanido (X=2) and Trisulfanido (X=3) Ligands
Treatment of CpRu(PPh(3))(CO)SH, 1 with the sulfur transfer reagents RSphth gave the complexes CpRu(PPh(3))-(CO)SSR (2a-c), where phth = phthalimido and R = 4-C(6)H(4)Me, (a), 1-C3H7, (b), and CHMe(2), (c), rare examples of complexes containing disulfanido ligands. Crystal data for 1 P ($) over bar 1, a = 9.408(11) Angstrom A, b = 10.6168(9) Angstrom A, c = 11.6499(5) Angstrom A, alpha 76.523(6)degrees, beta = 78.896(8)degrees, gamma = 78.562(8)degrees, V = 1314.9 Angstrom A(3), Z = 2. Crystal data for 2c : P2(1)/n, a = 9.274(2) Angstrom A, b = 11.345(3) Angstrom A, c = 25.303(6) Angstrom A, beta = 97.37(2)degrees, V = 2640.2 Angstrom A(3), Z = 4. Treatment of 1 with the disulfur transfer reagents RSSphth gave the complexes CpRu(PPh(3))(CO)SSSR (3a-c) possessing even rarer trisulfanido ligands. Crystal data for 3b : P ($) over bar 1, a = 10.643(2) Angstrom A, b = 14.040(3) Angstrom A, c = 9.205(3) Angstrom A, alpha = 98.11(2)degrees, beta = 97.26(2)degrees, gamma = 96.46(2)degrees, V = 1338.9 Angstrom A(3), Z = 2. The di- and trisulfanido ligands are resistant to loss of sulfur.
