Аннотация: The crystal structure of catena-di(mu(2)-2-thiobarbiturato-O,S)aqualead(II) C8H8N4O5S2Pb (C4H4N2O2S is 2-thiobarbituric acid, H(2)TBA) is determined. Crystallographic data for catena-[Pb(H2O)(mu(2)-HTBA-O,S)(2)] are as follows: a = 6.5972(1) , b = 9.8917(2) , c = 10.0893(2) , alpha = 106.702(1)A degrees, beta = 93.395(2)A degrees, gamma = 107.48(1)A degrees, V = 593.82(2) (3), space group , Z = 2. The Pb2+ ion is linked with six monodentate HTBA(-) ligands through two O atoms and four S atoms and also connected with a water molecule. Additionally, there is a shortened Pb-S contact (3.622 ), given which the complex polyhedron represents a distorted square antiprism. Hydrogen bonds N-HaEuro broken vertical bar O and O-HaEuro broken vertical bar O form a branched three-dimensional network. The structure is also stabilized by the pi-pi interaction of heterocyclic HTBA(-) ions.
