1-diphenylphosphino-1′-(diphenylphosphinoyl)cobaltocenium hexafluoridophosphate

The title compound, [Co(C17H14OP)(C17H14P)]PF6, was obtained unintentionally as the product of an attempted synthesis of [1,1′-bis(oxodiphenylphosphoranyl)cobaltocenium] hexafluoridophosphate. The O atom of the oxo group is disordered over two positions with site occupancies of 0.65:0.35. The crystal structure contains weak intermolecular C—H...F hydrogen bonds, connecting the components of the structure into chains parallel to [010].
