Synthesis and reaction chemistry of the coordinatively unsaturated heterobimetallic complexes (CO)3(PPh3)Fe(μ-PCy2)Rh(PPh3)(CO) and (CO)4Fe(μ-PCy2)Rh(1,5-COD). Crystal and molecular structure of (CO)3(PPh3)Fe(μ-PCy2)Rh(PPh3)(CO)

Reactions of Li[Fe(CO)4(PCy2)] with trans-RhCl(CO)(PPh3)2 and [RhCl(1,5-COD)]2 result in the formation of the μ-PCy2 complexes (CO)3(PPh3)Fe(μ-PCy2)Rh(PPh3)(CO) (2) and (CO)4Fe(μ-PCy2)Rh(1,5-COD) (3), respectively. These complexes are identified by 31P{1H} NMR and infrared spectroscopy, and 2 has been further characterized by a single-crystal X-ray diffraction study. It crystallizes in the space group P21/c with a = 23.746 (3) A?, b = 10.414 (2) A?, c = 19.823 (3) A?, β = 100.91 (1)°, V = 4813 (1) A?3, and Z = 4. The structure was refined to final R = 6.85% and Rw = 7.74% for 5041 reflections with Fo2 > 3σ(Fo2). The Fe atom has trigonal-bipyramidal geometry, coordinating to the bridging PCy2 group, one PPh3 ligand, and three CO groups. The Rh atom has a distorted-square-planar geometry coordinating to the bridging PCy2 group, one molecule of PPh3, one CO group, and the Fe atom. The Fe-Rh distance is 2.660 (1) A?, implying a metal-metal interaction, and one of the CO groups on the Fe atom is semibridging to the Rh atom. 2 reacts with CO to give the products (CO)3(PPh3)Fe(μ-PCy2)Rh(PPh 3)(CO2) (4) and (CO)4Fe(μ-PCy2)Rh(PPh3)(CO)2 (5) and with PEt3 to yield (CO)4Fe(μ-PCy2)Rh(PPh3)(CO) (6), (CO)4Fe(μ-PCy2)Rh(PEt3)(CO) (7), (CO)4Fe(μ-PCy2)Rh(PPh3)(PEt3) (8), and (CO)3(PPh3)Fe(μ-PCy2)Rh(PEt3)(CO) (9). 3 easily loses 1,5-COD under an atmosphere of CO(g) to yield (CO)4Fe(μ-PCy2)Rh(CO)x (x = 1-3). These reaction products (4-9) were identified in solution only, by 31P{1H} NMR.
