Аннотация: The crystal and molecular structures of thallium(I) thiobarbiturate C4H3N2O2STl (C4H4N2O2S is 2-thiobarbituric acid, H(2)TBA) have been determined. Crystallographic data for Tl(HTBA) are a = 11.2414(7) angstrom, b = 3.8444(3) angstrom, c = 14.8381(9) angstrom, beta = 99.452(2)degrees, V= 649.00(7) angstrom(3), space group P2/c, Z =Показать полностью4. Each of the two independent thallium ions is bonded to four oxygen and two sulfur atoms to form a distorted tetrahedron. N-H center dot center dot center dot O and C-H center dot center dot center dot S hydrogen bonds form a branched three-dimensional network. The structure is also stabilized by pi-pi interaction between heterocyclic HTBA(-) ions. The IR spectra of Tl(HTBA) agree with X-ray powder diffraction data. The compound is also stable below 280 degrees C, and Tl2SO4 is one of the thermolysis products in an oxidative medium in the region of 500-650 degrees C.
