'''Thallium(I) chloride''', also known as '''thallous chloride''', is a ] with the formula TlCl. This colourless salt is an intermediate in the isolation of ] from its ores. Typically, an acidic solution of ] is treated with ] to precipitate insoluble thallium(I) ]. This solid crystallizes in the ] motif.<ref>Holleman, A. F.; Wiberg, E. ''Inorganic Chemistry''. Academic Press: San Diego, 2001. {{ISBN|0-12-352651-5}}.</ref> |

The low solubility of TlCl is exploited in chemical synthesis: treatment of metal chloride ] with TlPF<sub>6</sub>, gives the corresponding metal ] derivative. The resulting TlCl precipitate is separated by filtration of the reaction mixture. The overall methodology is similar to the use of AgPF<sub>6</sub>, except that Tl<sup>+</sup> is much less oxidizing. |

The crystalline structure is of cubic caesium chloride type at room temperature, but it lowers to the ] ] type upon cooling, the transition temperature being likely affected by the impurities.<ref>{{cite journal|doi=10.1088/0370-1328/77/2/331|title=The Polymorphism of Thallium and Other Halides at Low Temperatures|journal=Proceedings of the Physical Society|volume=77|issue=2|pages=471|year=1961|last1=Blackman|first1=M|last2=Khan|first2=I H|bibcode=1961PPS....77..471B}}</ref> Nanometer-thin TlCl films grown on KBr substrates exhibit a ] structure, while the films deposited on ] or NaCl are of the regular CsCl type.<ref name=str>{{cite journal|doi=10.1107/S0365110X51001641|title=Polymorphism of cesium and thallium halides|journal=Acta Crystallographica|volume=4|issue=6|pages=487–489|year=1951|last1=Schulz|first1=L.

Thallium(I) chloride, like all thallium compounds, is highly toxic, although its low solubility limits its toxicity.<ref> {{Webarchive|url=https://web.archive.org/web/20190401160424/http://espimetals.com/index.php/722-msds/thallium-chloride/738-thallium-chloride |date=2019-04-01 }}. espimetals.com</ref> |
