[1,1′-Bis(di­phenyl­phosphan­yl)cobalto­cenium-κ²P,P′](η⁵-cyclo­penta­dien­yl){2-[4-(4-ethynylphen­yl)phen­yl]ethynyl-κC}ruthenium(II) hexa­fluorido­phosphate

In the title compound, [CoRu(C₅H₅)(C₁₆H₉)(C₁₇H₁₄P)₂]PF₆, the Ru^II atom is coordinated by a cyclo­penta­dienyl ring in an η⁵-mode, one C atom from a 4,4′-diethynyl-1,1′-biphenyl ligand and two P atoms from a chelating 1,1′-bis­(di­phenyl­phosphan­yl)cobaltocenium ligand, giving a three-legged piano-stool geometry. In the crystal, weak C—H...F hydrogen bonds link the complex cations and hexa­fluorido­phosphate anions into a three-dimensional supra­molecular structure.
