J. Casanova et al., METAL-COMPLEXES OF SULFANILAMIDE DERIVATIVES - CRYSTAL-STRUCTURE OF [ZN(SULFATHIAZOLE)2].H2O, Journal of inorganic biochemistry, 51(4), 1993, pp. 689-699
The crystal structure of the Zn(sulfathiazole)2 . H2O complex is repor
ted. The complex crystallizes in the monoclinic space group C2/c. The
cell dimensions are a = 9.098(3) angstrom, b = 17.871(5) angstrom, c =
14.61(1) angstrom, beta = 99.44(6)-degrees, V = 2343(2) angstrom3, Z
= 4, and D(x) = 1.68 g/cm3. The final conventional R-factor = 0.027 fo
r 2669 ''observed'' reflections and 191 variables. The Zn ion is surro
unded in a regular tetrahedral arrangement by two N(amino) and two N(t
hiazole) atoms pertaining to four sulfathiazole (Hstz) ligands. Each s
tz anion, acting as a bidentate ligand, chelates to two Zn ions as a b
ridge through the N(thiazole) and the N(amino) atoms. The IR, C-13 NMR
in solid state, H-1 NMR, and C-13 NMR in DMSO(d6) solutions spectra a
re discussed in detail with regard to the crystal structure.
