(R,R)-(N,N'-Diferrocenylcyclohexane-1,2-diyldiimino)dibenzonitrile

F. Chen

Abstract: In the title compound, [Fe₂(C₅H₅)₂(C₃₄H₃₄N₄)], two ferrocenes are bridged by a cyclohexane-1,2-diamine unit. The cyclopentadienyl 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, molecules are linked by C-HN interactions, forming an infinite two-dimensional network.
