(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.

[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.
