摘要:
                                A novel lithium biphenyl-2,2'-diyl(cyclopentadienyl)nickelate compound (9-nickelafluorenyllithium complex), ether)(2) (1), was prepared in the reaction between 2,2' dilithiobiphenyl and nickelocene in diethyl ether. Compound 1 was transformed to other 9-nickelafluorenyllithium compounds, [(1-(eta(5)-cyclopentadienyl))-1-nickelafluorenyl][lithium-(dimethoxyethane)(3)] (2) and (eta(5-)(1-(eta(5)-cyclopentadienyl))-1-nickelafluorenyl)lithium(dimethoxyethane) (3), whose crystal and molecular structures were determined by single-crystal X-ray analysis.
