Abstract
The X-ray crystal structure analysis of the 1 : 1 title complex is reported. Crystals are monoclinic, space group P21/c, with a= 6.172(5), b= 9.605(8), c= 20.33(2)Å, β= 96.60(8)°, and Z= 4. The structure has been solved from visually estimated data by the heavy-atom method, and refined by least-squares to R 10.2% for 1 865 non-zero observed reflections. Each silver atom is co-ordinated to three sulphadiazine molecules by a distorted tetrahedral configuration of three nitrogen atoms and one oxygen atom, with Ag–N 2.24, 2.24, and 2.44, and Ag–O 2.52 Å. The molecules are also linked by sheets of NH ⋯ OS hydrogen bonds as in related sulphonamide structures.Keywords
