In the title compound, [K(C7H6Cl2NO2S)(H2O)]n, the K+ cation is heptacoordinated by two water O atoms, a sulfonyl O atom from each of four different N,4-dichloro-2-methylbenzenesulfonamidate anions and a Cl atom of one of the anions. Further, K—O—K bridges form extensive polymeric chains along the b axis. In the the anions are linked into layers parallel to (100) by O—H⋯Cl and O—H⋯N hydrogen bonds.

The title compound was prepared by a method similar to the one described by Gowda & Mahadevappa (Gowda & Mahadevappa, 1983). 2 g of 2-methyl-4-chlorobenzenesulfonamide was dissolved with stirring in 40 ml of 5M KOH at 70° C. Pure chlorine gas was bubbled through clear aqueous solution for about 1 hr. The precipitated potassium salt of N-chloro-2-methyl-4-chlorobenzenesulfonamidate was filtered under suction, washed quickly with a minimum quantity of ice cold water. The purity of the compound was checked by determining its melting point (170 ° C) and estimating, iodometrically, the amount of active chlorine present in it. It was further characterized from its infrared spectrum.
Plate like colourless single crystals of the title compound used in the X-ray diffraction studies were obtained from its aqueous solution at room temperature.
The O-bound H atoms were located in difference map and were refined with restrained geometry (Nardelli, 1999), viz. O—H distances were restrained to 0.85 (2) Å and H—H distance was restrained to 1.365 Å, thus leading to the angle of 107°.
H atoms bonded to C were positioned with idealized geometry using a riding model with the aromatic C—H = 0.93 Å, methyl C—H = 0.96 Å. All H atoms were refined with isotropic displacement parameters set at 1.2 Ueq(C-aromatic, N, O) and 1.5 Ueq(C-methyl) of the parent atom.
The (6 1 1, -1 0 6, -10 1 1) reflections had a poor disagreement with their calculated values and were omitted from the refinement.
The crystal was refined with the

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. |

The present work was undertaken in order to explore the effect of replacing sodium ion by potassium ion on the solid state structures of metal salts of N-haloarylsulfonamidates(Gowda et al., 2007, 2011a,b,c), the structure of potassium N-chloro-2-methyl-4-chlorobenzene- sulfonamidate monohydrate (I) has been determined (Fig. 1). The structure of (I) resembles those of potassium N-chloro-benzenesulfonamidate monohydrate (II) (Gowda et al., 2007), potassium N-chloro-4-chlorobenzenesulfonamidate monohydrate (III) (Gowda et al., 2011b), potassium N-chloro-2-methyl-benzenesulfonamidate monohydrate (IV) (Gowda et al., 2011c) and other sodium N-chloroarylsulfonamidates (George et al., 2000; Olmstead & Power, 1986).
In the title compound, K+ ion is hepta coordinated by two O atoms from two different water molecules, sulfonyl O atoms of four different N-chloro-2-methyl-4-chlorobenzenesulfonamide anions and the Cl atom of the N—Cl bond in one of the N-chloro-2-methyl-4-chlorobenzene- sulfonamidate anions, similar to the coordination observed in II, III and IV. However, this is in contrast to the situation for potassium N-chloro-2-chlorobenzenesulfonamidate sesquihydrate (Gowda et al., 2011a) where the K+ cation acheives hepta coordination by binding three O atoms from three different water molecules and four sulfonyl O atoms of three different N-chloro-2-chlorobenzenesulfonamidate anions.
The S—N distance of 1.580 (6) Å is consistent with a S—N double bond and is in agreement with the observed values of 1.581 (4) Å in (II), 1.588 (2) Å in (III) and 1.584 (3) Å in (IV).
In the crystal structure the anions are linked by intermolecular O3—H32···Cl1 and O3—H31···N1 hydrogen bonding into layers (Fig. 2 and Table 1). Further, K– O –K bridges form extensive polymer chains along the b axis, generating a coordination polymer (Fig. 3).
