(Cycloheptatrienyl)(cyclopentadienyl)vanadium is an organovanadium compound with the formula V(C₅H₅)(C₇H₇). It is a purple, paramagnetic, sublimable solid that is sensitive toward air. The structure has been confirmed by X-ray crystallography.^[1] This sandwich complex features cyclopentadienyl and cycloheptatrienyl ligands bound to vanadium. It was first prepared by heating a mixture of cycloheptatriene and cyclopentadienylvanadium tetracarbonyl.^[2] Many derivatives of trovacene are prepared by lithiation of the cyclopentadienyl ring.^[3]
