The structure described by Tl2CrO4 crystallizes in the orthorhombic Pnma space group. Cr(1) is bonded in a tetrahedral geometry to one O(2), one O(3), and two equivalent O(1) atoms. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a 6-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. In the second Tl site, Tl(2) is bonded in a distorted single-bond geometry to one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Cr(1) and two equivalent Tl(1) atoms. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Cr(1) and two equivalent Tl(1) atoms. In the third O site, O(3) is bonded in a distorted linear geometry to one Cr(1) and one Tl(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
