Also known as thallium(I) cyclopentadienide
Cyclopentadienylthallium, also known as thallium cyclopentadienide, is an organothallium compound with formula C5H5Tl. This light yellow solid is insoluble in most organic solvents, but sublimes readily. It is used as a precursor to transition metal and main group cyclopentadienyl complexes, as well as organic cyclopentadiene derivatives.

==Preparation and structure== Cyclopentadienylthallium is prepared by the reaction of thallium(I) sulfate, sodium hydroxide, and cyclopentadiene: Tl2SO4 + 2 NaOH → 2 TlOH + Na2SO4 TlOH + C5H6 → TlC5H5 + H2O
