Tl4CO5 is Indium-like structured and crystallizes in the orthorhombic Cmc2_1 space group. The structure is zero-dimensional and consists of four Tl4CO5 clusters. There are three inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a distorted single-bond geometry to one O(1) atom. In the second Tl site, Tl(2) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(3) atoms. In the third Tl site, Tl(3) is bonded in an L-shaped geometry to two equivalent O(1) atoms. C(1) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to one Tl(1), one Tl(2), and one Tl(3) atom. In the second O site, O(2) is bonded in a single-bond geometry to one C(1) atom. In the third O site, O(3) is bonded in a distorted L-shaped geometry to one Tl(2) and one C(1) atom.
