(R,R)-N,N'-Bis(ferrocenylmeth-yl)cyclo-hexane-1,2-diamine.

In the structure of the title compound, [Fe(2)(C(5)H(5))(2)(C(18)H(24)N(2))], the cyclo-hexane ring has a chair configuration and the two ferrocenemethyl-amino groups are bonded to it equatorially, as expected. The configuration of the two ferrocence nuclei may be due to intra-molecular N-H⋯N hydrogen bonding involving the two NH groups.
