Treatment of (dppm=Ph2PCH2PPh2) with in benzene gave (1) in 90percent yield.The structure of (1) has been established by a single-crystal X-ray diffraction study; the crystals are monoclinic, space group P21/n, with a=1 246.5(2), b=1 849.0(3), c=1 612.3(2) pm, β=110.34(1) deg, and Z=4; final R factor 0.0481 for 4 053 observed reflections.The structure shows that there is a metal-metal bond , formulated as a donor - acceptor bond, viz.Fe - Rh.None of the carbonyl ligands shows any bridging interactions.Treatment of (1) with lithium acetate in dichloromethane-methanol converted the binuclear complex into the tetranuclear cluster (3) in 69percent yield, also characterised by an X-ray diffraction study.Crystals of (3) are monoclinic, space group P21/n, with a=2 074.6(5), b=1 385.1(3), c=2 271.6(5) pm, β=117.48(2) deg, and Z=4; final R factor 0.0578 for 6 212 observed reflections.The structure is that of an unsupported Fe2Rh2 butterfly, the Rh-Rh distance of 405.4 pm indicating no interaction between the wing-tip atoms.Similar complexes are described for Ph2P(C=CH2)PPh2.
