Cationic, four-co-ordinate, bis(organotransition metal)bismuth(III) complexes
Abstract
The ionic complex [Bi{OP(NMe2)3}2{Fe(CO)2(η-C5H5)}2][PF6] has been prepared and its crystal structure determined and compared with that of the valence isoelectronic anion [BiCl2{Fe(CO)2(η-C5H5)}2]–. Both structures have a four-co-ordinate bismuth centre with a geometry best described as equatorially vacant, trigonal bipyramidal in which the Fe(CO)2(η-C5H5) fragments are in the equatorial positions. The structure of [BiCl{Mo(CO)3(η-C5H4Me)}2] has also been determined and is compared with that of [BiCl{Mo(CO)3(η-C5H5)}2].
