Crystal structure of (E)-1,2-diferrocenyl-1,2-bis(furan-2-yl)ethene

Abstract

The title compound, [Fe2(C5H5)2(C20H14O2)], is the product of a new synthetic route towards tetraaryl/hetaryl-substituted ethenes that reduces the occurrence of side-products. In the crystal, the molecule is centrosymmetric and the cyclopentadienyl (Cp) rings are nearly coplanar and aligned slightly closer to a staggered conformation than to an eclipsed one. The ethene plane is tilted by 32.40 (18)° with respect to that of the substituted Cp ring and by 63.19 (19)° with respect to that of the furan ring. C—H...π interactions link the molecules into a three-dimensional supramolecular framework.
