(2E,6E)-2,6-Bis(ferrocenyl-methyl-idene)cyclo-hexa-none dichloro-methane monosolvate.

In the title compound, [Fe(2)(C(5)H(5))(2)(C(18)H(16)O)]·CH(2)Cl(2), the C=C bonds both adopt E conformations. In one ferrocenyl group, the five-membered rings are in a near-eclipsed conformation, whereas in the other they are mutually rotated by ca 21.5°. The central cyclo-hexa-none ring adopts a sofa conformation. In the crystal, the dichloro-methane solvent moleucle forms C-H⋯O hydrogen bonds to the organometallic mol-ecules to generate [010] chains of alternating solvent and organometallic species.
