摘要：

By reaction of [B6H6Hfac](-) with cobaltocene in acetonitrile [(C5H5)Co(C5H4)B6H5Hfac] is formed. Its crystal structure has been determined by single crystal X-ray diffraction analysis (monoclinic, space group P2(1)/n with a = 9.786(2), b = 9.726(2), c = 13.938(2) Angstrom, beta = 107.2850(3)degrees, Z = 4). The B-6 octahedron is slightly compressed in the direction of the B-C bond by about 1%, with B-B bond lengths between 1.69 and 1.87 Angstrom. The B-11 NMR spectrum exhibits a 1:4:1 pattern of a monosubstituted Bg cage. In the IR and Raman spectra characteristic B-H vibrations are observed.
