Thallium(I) fluoride

Thallium(I) fluoride (or thallous fluoride or thallium monofluoride) is the chemical compound composed of thallium and fluorine with the formula TlF. It consists of hard white orthorhombic crystals which are slightly deliquescent in humid air but revert to the anhydrous form in dry air. It has a distorted sodium chloride (rock salt) crystal structure, due to the 6s2 inert pair on Tl+. Thallium(I) fluoride is unusual among the thallium(I) halides in that it is very soluble in water, while the others are not.
