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

The title compound, [Fe-2(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)degrees with respect to that of the substituted Cp ring and by 63.19 (19)degrees with respect to that of the furan ring. C-H center dot center dot center dot pi interactions link the molecules into a three-dimensional supramolecular framework.
