Thallium(I) fluoride is the inorganic compound with the formula TlF. It is a white solid, forming orthorhombic crystals. The solid is slightly deliquescent.[1] It has a distorted sodium chloride (rock salt) crystal structure,[3][4] due to the 6s2 inert pair on Tl+.[5]
This salt is unusual among the thallium(I) halides in that it is very soluble in water.[6]
