摘要：

The reaction of [Me2AlC=CR]2, 1 (R = cyclohexyl), with an equimolar quantity of Cp2HfMe2, 2 gave the dimetallic mixed metal complex CP2Hf(mu-eta-1:eta-2-MeCCR)(mu-CCR)AlMe2, 3 and trimethylaluminium. An X-ray diffraction study of 3 revealed that it has a planar tetracoordinate carbon atom (C3) bridging between hafnium and aluminium. The four bond distances in the central plane to C3 are 1.280(9) [C3-C1], 1.562(8) [C3-C4], 2.091(6) [C3-Al], and 2.432(6) [C3-Hf] angstrom.
