Abstract
By powder X-ray diffraction the crystal structure of catena-(2-thiobarbiturato)dithallium(I) C4H2N2O2STl2 (C4H4N2O2S is 2-thiobarbituric acid, H2TBA), Tl2TBA, is determined. Crystallographic data for Tl2TBA are as follows: a = 15.1039(3) Å, b = 12.0818(2) Å, c = 3.86455(6) Å, β = 97.203(1)°, V = 741.34(2) Å3, space group P21/n, Z = 4. There are two non-equivalent thallium atoms in the structure. The Tl1 polyhedron is a distorted trigonal prism due to the shortened Tl-S contact (3.634 Å), and the Tl2 polyhedron is a distorted square antiprism.
