title: Crystal structure of 1,1'-bis-(2-meth-oxy-carbonyl-2-methyl-prop-yl)ferrocene.
abstract: The Fe atom in the title ferrocene derivative, [Fe(C11H15O2)2], is situated on an inversion centre. As a result of the point-group symmetry -1 of the mol-ecule, the ferrocene moiety adopts a staggered conformation. The average Fe-C(Cp) bond length (Cp is cyclo-penta-dien-yl) is 2.045 (4) Å, in agreement with that of other disubstituted ferrocenes. The Fe-C bond length involving the substituted C atom is slightly longer [2.0521 (17) Å] than the remaining Fe-C bond lengths caused by the inductive effect of the methyl-ene group on the Cp ring. Apart from van der Waals forces, no significant inter-molecular inter-actions are observed in the crystal packing.
