title: Structure of 2,2,2-tricarbonyl-1,1-bis(ethylene)-mu-(eta 5:eta 5-fulvalene)-2-methylrhodiumtungsten.
abstract: [RhW(C10H8)(CH3)(C2H4)2(CO)3], Mr = 570.10, monoclinic, P2(1)/c, a = 7.3358(8), b = 10.8640(15), c = 21.6310(20) A, beta = 90.924(8) degrees, V = 1723.7(3) A3, Z = 4, Dm = 2.16, Dx = 2.196 g cm-3, lambda(Mo K alpha) = 0.71069 A, mu = 77.7 cm-1, F(000) = 1080, T = 298 K, R = 0.021, wR = 0.029 for 4453 observed reflections with I greater than or equal to 3 sigma(I). The compound is a bimetallic fulvalene complex with rhodium and tungsten oriented trans to each other across an essentially planar fulvalene dianion.
