Abstract

Organometallic compounds of the alkali metals which contain symmetrical bridging cyclopentadienyl groups, i.e., those in which two metal centers are located at equal distance on either side of and on the pseudo C{sub 5}-axis of the cyclopentadienyl group, are rare; the only example is the linear zigzag polymeric structure of (Na(Me{sub 2}NCH{sub 2}CH{sub 2}NMe{sub 2})Cp). The authors describe the synthesis and x-ray crystal structure of (Li-(Me{sub 2}NCH{sub 2}CH{sub 2}NMe{sub 2}){sub 2}){center dot}(Li(Me{sub 2}NCH{sub 2}CH{sub 2}NMe{sub 2})){sub 2}({mu}-MeC{sub 5}H{sub 4}){center dot}((MeC{sub 5}H{sub 4}){sub 3}U){sub 2}({mu}-Me), a compound that contains a MeC{sub 5}H{sub 4} group sandwiched between two Li(Me{sub 2}NCH{sub 2}CH{sub 2}NMe{sub 2}) fragments and a methyl group that is symmetrically bridging between two (MeC{sub 5}H{sub 4}){sub 3}U groups.
