Abstract
The crystal structure of the Zn(sulfathiazole) 2·H 2O complex is reported. The complex crystallizes in the monoclinic space group C2/ c. The cell dimensions are a = 9.098(3) Å, b = 17.871(5) Å, c = 14.61(1) Å, β = 99.44(6)°, V = 2343(2) Å 3, Z = 4, and D x = 1.68 g/cm 3. The final conventional R-factor = 0.027 for 2669 “observed” reflections and 191 variables. The Zn ion is surrounded in a regular tetrahedral arrangement by two N amino and two N thiazole atoms pertaining to four sulfathiazole (Hstz) ligands. Each stz anion, acting as a bidentate ligand, chelates to two Zn ions as a bridge through the N thiazole and the N amino atoms. The IR, 13C NMR in solid state, 1H NMR, and 13C NMR in DMSO d6 solutions spectra are discussed in detail with regard to the crystal structure.
