the appropriate tripodal tetradentate ligands, L = N(CH2CH2PPh2)3 or P(CH2CH2PPh2)3, are reported. These monoligand trimetallic compounds contain two Rh(C5Me5)Cl2 units each bound to a terminal phosphorus atom of the tripod ligand and a Rh(C5Me5)Cl group linked to the third terminal phosphorus and to the apical donor atom, nitrogen for N(CH2CH2PPh2)3, phosphorus for P(CH2CH2PPh2)3. The Rh(C5Me5)Cl group
