摘要
The crystal structure of catena-(mu(4)-1,3-diethyl-2-thiobarbiturato-O,O',S,S)silver(I) [Ag(mu(4)-DETBA-O,O',S,S] (1), where HDETBA is 1,3-diethyl-2-thiobarbituric acid C8H12N2O2S, has been solved by X-ray powder diffraction. Crystals of complex 1 are monoclinic, a = 7.8339(2) , b = 15.4970(4) , c = 8.7502(2) , beta = 111.916(2)A degrees, V = 985.53(5) (3), space group P2(1)/c, Z = 4. The Ag+ ion is coordinated by two oxygen atoms and two sulfur atoms to form a distorted tetrahedron. Tetrahedra share sulfur atom vertices to form infinite chains linked via bridging DETBA(-) ions into a three-dimensional framework. No hydrogen bonds have been found in the structure, but pi-pi interaction is observed between DETBA(-) ions.
