Neutral thiolates of antimony(III) and bismuth(III)
摘要:
A range of bismuth(III) and antimony(III) thiolates, Bi(SR)(3) (R = C6F5, 4-MeC(6)H(4), 2,6-Me(2)C(6)H(3) or 3,5-Me(2)C(6)H(3)) and Sb(SR)(3) (R = 4-MeC(6)H(4) or 3,5-Me(2)C(6)H(3)) has been synthesised and the structures of the two antimony complexes have been determined. Both structures reveal a trigonal-pyramidal antimony centre bonded to three thiolate groups with; far the 4-MeC(6)H(4) complex. additional intermolecular Sb ... S interactions and, for the 3,5-Me(2)C(6)H(3) complex intermolecular arene to antimony interactions. The syntheses and structures of the organotransition-metal complexes [Bi(SC6F5){M(CO)(3)(eta-C5H5)}(2)] (M = Mo or W) are also reported in which the bismuth centre is bonded to one SC6F5 group and two M(CO)(3)(eta-C5H5) fragments with no short intermolecular interactions.
