Crystal structure of 1,1′,2,2′,4,4′-hexa­iso­propyl­magnesocene

The title compound, 3Cp2Mg or [Mg(C14H23)2], was synthesized from the cor­res­ponding triiso­propyl­cyclo­penta­diene by treatment with n-butyl-sec-butyl­magnesium. The structural characterization by single-crystal X-ray diffraction revealed that the compound crystallizes in the triclinic space group PUnlabelled Image with half a mol­ecule per asymmetric unit and a staggered arrangement of the cyclo­penta­dienide ligands.
