The material structure described by CuTl2(CO3)2 crystallizes in the monoclinic P2_1/c space group. Cu(1) is bonded in a distorted trigonal bipyramidal geometry to one O(1), one O(2), one O(3), one O(4), and one O(5) atom. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a 4-coordinate geometry to one O(1), one O(2), one O(4), and one O(6) atom. In the second Tl site, Tl(2) is bonded in a distorted L-shaped geometry to one O(2) and one O(6) atom. There are two inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(4) atom. In the second C site, C(2) is bonded in a trigonal planar geometry to one O(3), one O(5), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(6) is bonded in a distorted single-bond geometry to one Tl(1), one Tl(2), and one C(2) atom. In the second O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Cu(1), one Tl(1), and one C(1) atom. In the third O site, O(2) is bonded in a 2-coordinate geometry to one Cu(1), one Tl(1), one Tl(2), and one C(1) atom. In the fourth O site, O(3) is bonded in a bent 120 degrees geometry to one Cu(1) and one C(2) atom. In the fifth O site, O(4) is bonded in a distorted single-bond geometry to one Cu(1), one Tl(1), and one C(1) atom. In the sixth O site, O(5) is bonded in a bent 120 degrees geometry to one Cu(1) and one C(2) atom. is represented by the CIF file [CIF]
