title: (R,R)-(N,N'-Diferrocenylcyclo-hexane-1,2-diyldiimino)dibenzonitrile.
abstract: In the title compound, [Fe(2)(C(5)H(5))(2)(C(34)H(34)N(4))], two ferrocenes are bridged by a cyclo-hexane-1,2-diamine unit. The cyclo-penta-dienyl rings of the two ferrocene units are almost parallel [dihedral angles of 0.7 (4) and 1.0 (4)° in the two units] and eclipsed, as is typically found for similar monosubstituted ferrocene derivatives. The dihedral angle formed by the two benzene rings is 20.2 (3)°. The Fe-C bond lengths to the two substituted Cp rings vary from 2.014 (4) to 2.070 (3) Å, and are in the normal range. In the crystal, mol-ecules are linked by C-H⋯N inter-actions, forming an infinite two-dimensional network.
