摘要：

The reactions of (dpp-BIAN)Zn-Zn(dpp-BIAN) (1) with PhC CH and of [(dpp-BIAN)Zn(mu-I)](2) (2) with potassium hydride yield the binuclear complexes [(dpp-BIAN)Zn(mu-C CPh)](2) (3) and [(dpp-BlAN)Zn(mu-H)](2) (4), respectively (dpp-BIAN = 1,2-bis[(2,6-diisopropylphenyl)imino] acenaphthene). Complex 3 is also obtained by thermal dehydrogenation of [dpp-BIAN(H)]Zn-(C CPh) (5), which in turn can be prepared by reacting ZnI2, with equimolar amounts of [dpp-BIAN(H)]Na and PhC CNa. The paramagnetic compounds 3 and 4 have been characterized by ESR spectroscopy; the diamagnetic complex 5, by H-1 NMR spectroscopy. The molecular structures of 3 and 4 have been determined by single-crystal X-ray diffraction. The electronic structure of complex 4 has been examined by DFT.
