Unsaturated, PCy2-bridged Re-M heterobimetallics (M = Rh, Ir, Pd; Cy = Cyclohexyl): Metal-metal bond isomerism, reversible P-H bond activation, and cooperative reactivity

The new d4-d8 heterobimetallics (PCy2)2Re(μ-PCy2)2M(1,5-COD) (M = Rh, Ir; COD = cyclooctadiene) are proposed, on the basis of 31P DNMR, to exist in two isomeric forms: one with pseudotetrahedral (PT) coordination about M and an M=Re double bond and the other with square-planar (SP) coordination about M and an M→Re donor-acceptor bond. Structural models for this metal-metal bond isomerism are provided by (PCy2)2Re(μ-PCy2)2Ir(PMe 3)2 (PT, Re-Ir = 2.6573 (5) A?) and [(PCy2)2ReH(μ-PCy2) 2Rh(1,5-COD)]BF4 (SP, Re-Rh = 2.9361 (8) A?). Reversible P-H bond activation is observed for (PCy2)(PCy2H)(N2)Re(μ-PCy2) 2Pd(PPh3)(Pd=Re) and (PCy2)2ReH(μ-PCy2)2Pd(PPh 3)(Pd→Re) and carbonylation of the Ir-COD complex occurs at both metal centers to give (PCy2)(CO)2Re(μ-PCy2)2Ir(CO) 2(PCy2) in which a PCy2 ligand has been transferred to Ir.
