摘要:
                                Reaction of [MoCl2(CO)4] with the 2,6-diphenylthiophenolate anion (dpt) gives the complex [Mo(eta-6-dpt)(dpt)(CO)], with one thiol phenyl substituent eta-6-bonded to the molybdenum.  Crystal data:  space group P2(1)/c with a = 13.939(3), b = 10.548(3), c = 20.863(5) angstrom, beta = 106.88(1)-degrees and Z = 4.  The eta-6-arene ligand is labile and is reversibly replaced by CO.  Replacement of this ligand also occurs with 2,2'-bipyridyl(dipy),1,10-phenanthroline (phen), and 1,2-bis(diphenylphosphino)ethane (dppe) to give the dicarbonyl complexes [Mo(dpt)2(CO)2L] (L = bipy or phen) or the monocarbonyl complex [Mo(dpt)2(CO)(dppe)].  The X-ray crystal structure of the bipy derivative and the mechanism of its formation is discussed.  Crystal data:  space group P2(1)/c with a = 10.567(3), b = 22.843(5), c = 18.341(3) angstrom, beta = 105.2(2)-degrees and Z = 4.  Reaction of RhCl3 with dpt gave the dinuclear species [Rh2{mu-SC6H3(C6H4)-2-Ph-6}2(dpt)2(NCMe)2].  An X-ray crystal structure reveals that each bridging thiolate ligand is also sigma-bonded to rhodium [Rh-C 2.016(8) angstrom] via one of the phenyl carbons of the thiolate substituents.  Crystal data:  space group P2(1)/n, a = 11.991(2), b = 20.426(4), c = 15.910(4) angstrom, beta = 90.42(1) and Z = 2.
