Cyclopentadienylthallium is an organothallium compound. It may be prepared by the reaction of aqueous thallium hydroxide solution with cyclopentadiene, from which mixture it precipitates as air-stable yellow crystals.[1]
The bonding mode of the cyclopentadienyl ligand is η5. In the gas phase, the compound is monomeric, with the thallium atom sitting 241 pm above the plane of the cyclopentadienyl ring,[1] while the crystal structure has zigzag chains of equidistant thallium cations and cyclopentadienide anions.[1]
