(1R,2R)-N,N′-Bis(ferrocenylmeth­yl)-1,2-diphenyl­ethane-1,2-diamine

The title compound, [Fe2(C5H5)2(C26H26N2)], was synthesized from a chiral diamine and ferrocenecarboxaldehyde and subsequent reduction with NaBH4. It has two chiral centers which both exhibit an R configuration. Two ferrocene groups are present in the mol­ecular structure, with their cyclo­penta­dienyl ring planes showing an almost perpen­dicular arrangement [dihedral angle 88.6 (1)°].
