Abstract
Complexes of rhodium(I) with carbon monoxide, bis(diphenylphosphino)methane (dppm), or the arsine analogue (dpam), and a variety of anionic ligands are described, and the natures of each of the novel complexes are compared with those of known complexes containing terminal or bridging chloro-ligands. In solution in acetone–methanol and in the presence of halide ions (X = Cl–, Br–, or I–) cationic dinuclear ‘A-frame’ complexes [Rh2(µ-X)(CO)2L2]+ and [Rh2(µ-X)(µ-CO)(CO)2L2]+(L = dppm or dpam) are readily formed. In the presence of the pseudohalide ions (Z = CN– or SCN–) the neutral complexes [Rh2Z2(CO)4L2] are initially formed. The cyano-complexes readily dissociate one (dppm) or two (dpam) moles of CO respectively. When Z is OCN– or N3 – the products are dinuclear dicarbonyl complexes [Rh2Z2(CO)2L2].Keywords
