The title complex, [Mn(C12H9N2O3S)2]·2H2O, is isotypic with the previously reported ZnII and CdII species. The complex was prepared by the reaction of the potassium salt of 2-(2-pyridylmethyleneamino)benzenesulfonic acid with MnCl2·6H2O in methanol. The complex displays twofold symmetry, with the ligands coordinated in a tridentate meridional-like arrangement through pyridyl N, imine N, and sulfonate O atoms. The metal center has a strongly distorted octahedral coordination geometry. The uncoordinated water molecules and the complexes participate in a hydrogen-bonding network, forming a two-dimensional structure parallel to the ab plane.

The potassium salt of 2-(2-pyridylmethyleneamino)benzenesulfonic acid (PabaK) was synthesized according to the literature methods (Casella & Gullotti, 1986). The ligand PabaK (1 mmol, 0.30 g) was dissolved in methanol (10 ml). To this solution, MnCl2 6 H2O (0.5 mmol, 0.12 g) was added, and the resulting mixture was stirred at 333 K for 4 h. Then the mixture was filtrated and the filtrate was left to stand at room temperature. Yellow crystals suitable for X-ray diffraction were obtained after a week in a yield of 55%. Elemental analysis: found C 46.87, H 4.04, N 9.05, S 10.42%; calc. C 46.94, H 3.59, N 9.13, S 10.43%.
C-bonded H atoms were positioned geometrically with C—H distances of 0.93 Å, and treated as riding atoms, with Uiso(H) = 1.2 Ueq(carrier C). Water H atoms were placed in fixed positions and assigned Uiso values of 1.5 Ueq of the water O atom.

In the past decades, Schiff-base complexes containing sulfonate have received much attention owing to the diverse coordination modes and bridging ability (Zhang et al., 2005; Li et al., 2007; Ou-Yang et al., 2009). Herein, we prepared a mononuclear Mn(II) complex, which is isostructural with [Zn(Paba)2].2 H2O and [Cd(Paba)2].2 H2O, whose structures were described in details (Cai et al., 2008; Ou-Yang et al., 2008). The six-coordinated MnII ion lies on a twofold axis, and two deprotonated PabaH anions coordinate to Mn in a meridional arrangement as N,N',O-tridentate donor ligands. The coordination mode of the complex is similar to that observed in other complexes with N,N',O-tridentate donor ligands (Li et al., 2007, 2008; Correia et al., 2003).
The O—H donor groups from the lattice water molecules and the SO acceptor groups of the Paba ligands participate in the hydrogen bonding through which the complex completes a two-dimensional network parallel to the ab plane (Fig. 2).
