Abstract
The crystal and molecular structure of the red brown form of [Fe2(η5-C5H4Me)2(CO)(CN)(μ-CO) · (μ-CNMe2)] has been determined by X-ray crystallography. It crystallises with one molecule per asymmetric unit (P21/c) and CO/CN disorder among the terminal ligands. It is a cis isomer with a non-planar Fe2(μ-C)2 bridge having a dihedral angle of 154° between the two Fe2C planes. The Fe—C distances to the 2-electron donor ligands (CO, CN, μ-CO and μ-CNMe2+) can be rationalised on the basis of their σ donor and π acceptor abilities.
