Abstract
The chelate olefin complex RhCl(o-Ph2P·C6H4·CH:CH·C6H4·PPh2-o) is formed by dehydrogenation of 2,2′-bis(diphenylphosphino)bibenzyl, o-Ph2P·C6H4·CH2·CH2·C6H4·PPh2-o, in the presence of RhI or RhIII compounds, and is shown to be essentially square planar by X-ray structural analysis; four- and five-co-ordinate iridium(I) complexes are also formed by the tridenate olefinic ligand.Keywords
