摘要
The synthesis, spectroscopic characterization and crystal structure of [RuCl3(TMSO)(2)(CO)] (1) and [H(TMSO)(2)]- [RuCl4(TMSO)(CO)] (2) are reported. These complexes are prepared by the reaction of the precursors (mer-RuCl3(TMSO)(3)] and [H(TMSO)][RuCl4(TMSO)(2)] with carbon monoxide in the presence or absence of TMSO at ambient temperature and pressure. Complexes 1 and 2 represents the first examples of Ru(III) compounds bearing both tetramethylene sulfoxide and carbon monoxide ligands on the metal. Substitution of one of the two trans-S-bonded TMSO from the anion accompanied addition of one molecule of TMSO on the cation. Coordination of CO induces an S-to-O linkage isomerization of the TMSO ligands. The crystal of 1 is a red-orange needle, monoclinic, space group C2/c, a = 26.446(2) Angstrom, b = 8.8726(6) Angstrom, c = 15.1093(8) Angstrom beta = 107.427(4)degrees. The crystal of 2 is an orange needle, orthorhombic, space group Pnma, a = 11.9820(9) Angstrom, b = 14.1930(11) Angstrom, c = 12.6500(15) Angstrom. (C) 2001 Elsevier Science B.V. All rights reserved.
