In the title compound, [Ca(C8H8N3O3S2)2(H2O)4], the Ca atom (site symmetry ) adopts a slightly distorted octahedral CaO6 geometry and the molecular conformation is stabilized by intramolecular N—H⋯N interactions. In the crystal, the molecules are linked by O—H⋯O, O—H⋯S, N—H⋯O and N—H⋯S hydrogen bonds.

A solution of 1.0 mmol 2-formyl-benzenesulfonate-thiosemicarbazide was added to a solution of 0.5 mmol Ca(ClO4)2.4H2O in 5 ml e thanol at room temperature. The mixture was refluxed for 4 h with stirring, then the resulting precipitate was filtered, washed, and dried in vacuo over P4O10 for 48 h. Colourless blocks of (I) were obtained by slowly evaporating from methanol at room temperature.

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. |

Schiff base metal complexes have been of interest in coordination chemistry for many years due to their facile synthesis, strong coordination function and wide applications (e.g. Sawant, et al., 2009). Ca complexes with Schiff base ligand have received little attention. In this paper, we report on the synthesis and crystal structure of the title compound, (I), (Scheme I).
The Ca(II) center is Six-coordinate with two O donors of 2-formyl-benzenesulfonate-thiosemicarbazide ligands and four O donors of coordinated water molecules, and adopts distorted octahedral coordination. The bond distances of Ca—O are in the range of 2.310 (4)–2.362 (4), which are consistent with the bond lengths reported previously. In the crystal packing, the molecules form a one-dimensional chain structure by the interaction of hydrogen bonds.
