The compound described by TlCHO2 crystallizes in the orthorhombic Pna2_1 space group. Tl(1) is bonded in a distorted L-shaped geometry to two equivalent O(1) and two equivalent O(2) atoms. C(1) is bonded in a trigonal planar geometry to one H(1), one O(1), and one O(2) atom. H(1) is bonded in a single-bond geometry to one C(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Tl(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Tl(1) and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
