N,N′-Diphenylguanidine reacted with the hydrido complexes [MH2(CO)(PPh3)3] (M = Ru or Os) and mer-[IrH3(PPh3)3] in boiling toluene to afford the complexes [MH{PhNC(NH2)NPh} (CO)(PPh3)2] and [IrH2{PhNC(NH2)NPh}(PPh3)2] in which the N,N′-diphenylguanidinate anions adopt a symmetrical chelate coordination mode. Under similar conditions the trifluoroacetato complexes [M(O2CCF3)2(CO)(PPh3)2] afforded salts [M{PhNC(NH2)NPh} {PhNC(NH2)NPh·H}(CO)(PPh3)2][O 2CCF3] containing one chelate N,N′-diphenylguanidinate anion and one monodentate N,N′-diphenylguanidine ligand. Spectroscopic evidence indicates that the trifluoroacetate anions are hydrogen bonded to one or more of the N-bound hydrogens.
