N3)[(2-oxidobenzylideneamino)methanesulfonato-2N,O]zinc(II)The ZnII ion in the title complex, [Zn(C9H4NO4S)(C3H4N2)2], is coordinated by an N atom and an O atom of a deprotonated tridentate Schiff base ligand, and two N atoms from two different imidazole ligands in a distorted tetrahedral geometry. In the crystal structure, molecules are connected via intermolecular N-H
O hydrogen bonds, forming extended one-dimensional chains along [111].
The potassium salt of the Schiff base ligand [(2-Hydroxy-benzylidene)-amino]-methanesulfonic acid, L, was synthesized according to the approach of Li et al. (2005). L (1.0 mmol) in 10 ml me thanol was added dropwise to a stirred solution of ZnCl2 (1.0 mmol) in 5 ml me thanol and 5 ml water. To this mixed solution, a solution of 1H-Imidazole (2.0 mmol) in 5 ml me thanol was added slowly. The resulting yellow solution was filtered and left to stand for two weeks to evaporate slowly at room temperature to give yellow prism-shaped single crystals in yield of 55%.
H atoms were fixed geometrically and allowed to ride on their attached atoms, with C—H distances 0.93Å and N—H distances 0.86 Å, and with Uiso(H) = 1.2Ueq(C,N).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

There is considerable interest in the study of Schiff-base complexes containing sulfur and complexes of amino acid Schiff-bases (Deng et al., 2006; Jiang et al., 2006; Casella et al., 1981,1986) due to their antiviral, anticancer and antibacterial activities. Herein, we report the synthesis and crystal structure of the title zinc(II) complex. The ZnII cation is coordinated by one N atom and one O atom of a deprotonated tridentate schiff base ligand and two N atoms (Fig.1 and Table.1) from two different 1H-Imidazole ligands in a distorted tetrahedral geometry. In the crystal structure, molecules are connected via intermolecular N—H···O hydrogen bonds to form extended one-dimensional chains along [111].
