(Cycloheptatrienyl)(cyclopentadienyl)titanium is an organotitanium compound with the formula Ti(C<sub>7</sub>H<sub>7</sub>)(C<sub>5</sub>H<sub>5</sub>). 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 ÃÂ .
The complex can be prepared by the reaction of titanocene dichloride, butyllithium, and cycloheptatriene.
