The X-ray structure of an unsymmetrical tetraphosphine bridged zwitterionic Rh-IRhI dinuclear tetracarbonyl complex is reported along with the facile CO addition equilibrium to form an Rh0 tetraphosphine pentacarbonyl bimetallic species; both of these are poor hydroformylation catalysts due to the relatively high electron density on the rhodium centres, in marked contrast to a dicationic bimetallic RhII complex based on the same tetraphosphine ligand that is a highly active and regioselective hydroformylation catalyst.
