Abstract The new thallium hydroxocarbonate Tl4(OH)2CO3 has been obtained by evaporation from aqueous solution. The crystal structure of the compound has been solved by direct methods: orthorhombic, Cmc21, a = 8.9963(18), b = 12.1500(30), c = 7.9542(15) Å, V = 869.43(3) Å3, R1 = 0.056 for 763 unique reflections with |Fo| ≥ 4σF. There are three symmetrically independent Tl+ cations in the structure. The O atoms of the OH- groups are triangularly coordinated by three Tl atoms that results in…
