Diberyllocene: xyz-coordinates of optimized structures
The complex diberyllocene, CpBeBeCp (Cp = cyclopentadienyl anion), has been the subject of numerous chemical investigations over the past five decades, yet has eluded experimental characterization. Here we report preparation and isolation of the compound by the reduction of beryllocene (BeCp2) with...

The complex diberyllocene, CpBeBeCp (Cp = cyclopentadienyl anion), has been the subject of numerous chemical investigations over the past five decades, yet has eluded experimental characterization. Here we report preparation and isolation of the compound by the reduction of beryllocene (BeCp2) with a dimeric magnesium(I) complex and determination of its structure in the solid state by x-ray crystallography. Diberyllocene acts as a reductant in reactions that form beryllium bonds to aluminum or zinc.
