The ligand PNNHP has been prepared. It is a planar quadridentate ligand consisting of a central pyrazole unit with symmetrically disposed methylenediphenylphosphine arms, and its geometry provides for two metals to reside within cooperative distance but does not allow for metal-metal bond formation. Two types of planar bimetallic complexes have been isolated and characterized: those with anionic bridging groups (X) of the composition [M2(PNNP)(X)L2] (M = Pd(II), X = Cl, L = Cl; M = Rh(I), X = Cl and PPh2, L = CO; M = Ir(I), X = PPh2, L = CO) and those without bridging atoms of the composition [M2(PNNP)L4]+ (M = Pd(II), 2L = π-allyl; M = Rh(I) and Ir(I), 2L = diene and L = CO) have been identified.
