Аннотация: The crystal and molecular structure of potassium thiobarbiturate C4H3KN2O2S (C4H4N2O2S-2-thiobarbituric acid, H(2)TBA) is determined. Crystallographic data for KHTBA are as follows: a = 11.2317(17) , b = 3.8687(6) , c = 14.557(2) , beta = 97.448(4)A degrees, V = 627.18(17) (3), space group P2/c, Z = 4. Each potassium ion is linked Показать полностьюwith four oxygen atoms and two S atoms forming a distorted octahedron. N-HaEuro broken vertical bar O and C-HaEuro broken vertical bar S hydrogen bonds form a branched three-dimensional network. The structure is also stabilized by the pi-pi interaction of heterocyclic HTBA(-) ions.
