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

Disubstituted Cyclohexanes: cis-trans Isomerism
In cyclohexane, the substituents can occupy different positions generating distinct isomers.
Stability of Substituted Cyclohexanes
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.
