摘要：

Novel -C(CH3)2- bridged molecules, (CH3)2C(C5H4)2M(CH3)2, M=Ti, Zr, were synthesized. The structures of both molecules were determined by X-ray diffraction analysis. For the Ti compound: crystals, monoclinic; space group, P2(1)/m, a = 7.196(4), b = 10.227(1), c = 8.941(3) angstrom, gamma = 89.95-degrees. For Zr compound: crystals, monoclinic; space group P2(1)/m, a = 7.333(4), b = 10.429(3), c = 9.031(6) angstrom, gamma = 89.98-degrees. Both molecules are characterized, as expected, by significant intramolecular tension resulting in obvious distortion of the sandwich moiety.
