Article abstract of DOI:10.1039/DT9810000228

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(1-), Br(1-), or I(1-) cationic dinuclear 'A-frame' complexes (1+) and (1+) (L=dppm or dpam) are readily formed.In the presence of the pseudohalide ions (Z=CN(1-) or SCN(1-)) the neutral complexes are initially formed.The cyanocomplexes readily dissociate one (dppm) or two (dpam) moles of CO respectively.When Z is OCN(1-) or N3(1-) the products are dinuclear dicarbonyl complexes .
