| الوصف: | The dimers (CpMCl)2(µ-Cl)2] (Cp* = 5-C5Me5) react with N-pyridin-2-ylmethyl-N', N¿-bis-(2, 6-diisopropylphenyl)guanidine (H2L) in the presence of NaSbF6, giving rise to chlorido compounds of formula CpMCl(¿2N, N'-H2L)]SbF6] (M = Rh, 1; Ir, 2), in which the guanidine ligand adopts a ¿2N, N' chelate coordination mode. Compounds 1 and 2 react with NaOH, rendering the complexes CpM(¿3N, N', N¿-HL)]SbF6] (M = Rh, 3; Ir, 4), in which the HL ligand exhibits a fac ¿3N, N', N¿ coordination. Complexes 3 and 4 activate the H-H and O-H bonds of dihydrogen and water. The hydrido complex CpIrH(¿2N, N'-H2L)]SbF6] (6) was isolated from the reaction of the iridium complex 4 with H2. In the reaction of the rhodium complex 3 with D2O, its Cp* ligand is gradually and reversibly deuterated. A plausible mechanism for this H/D exchange is proposed. The new complexes have been characterized by analytical and spectroscopic means, including the determination of the crystal structures of the compounds 1-4 and 6 by X-ray diffractometric methods. © |
