(Cycloheptatrienyl)(cyclopentadienyl)titanium

(Cycloheptatrienyl)(cyclopentadienyl)titanium is an organotitanium compound with the formula Ti(C7H7)(C5H5). It is a blue, diamagnetic, sublimable solid that is sensitive toward air. The structure has been confirmed by X-ray crystallography. This sandwich complex features cyclopentadienyl and cycloheptatrienyl ligands bound to titanium. The Ti-C distances are all within a narrow range near 2.35 Å.

The complex can be prepared by the reaction of titanocene dichloride, butyllithium, and cycloheptatriene.
