Crystal structure of (η2,η2-cycloocta-1,5-diene)(η5-indenyl)cobalt(I)

Abstract

The title compound, [Co(C8H12)(C9H7)], was synthesized by the reaction of metallated 2-H-indene with CoCl(PPh3)3and 1,5-cyclooctadiene in tetrahydrofuran/toluene. In the molecule, the CoIatom is coordinated by the two double bonds of the 1,5-cyclooctadiene ligand and η5-bonded to the indenyl ligand. The asymmetric unit contains two molecules of the CoIcomplex with very similar conformations. In the crystal, molecules are arranged into rows parallel to [100]. Apart from dispersion forces, there are no notable intermolecular interactions in the crystal.
