In the title compound, C12H13NO3S, a saccharin derivative, the dihedral angle between the aromatic and isothia­zole rings is 2.91 (12)°. The planar 3,3-dimethyl­allyl group [maximum deviation = 0.0086 (16) Å] is oriented at dihedral angles of 71.86 (7) and 74.35 (7)° with respect to the aromatic and isothia­zole rings, respectively. In the crystal structure, weak inter­molecular C—H⋯O inter­actions link the mol­ecules into chains along the c axis. A weak C—H⋯π inter­action is also present.

Comment top

The sodium salt of 1,2-benzisothiazole-3(2H)-one-1,1-dioxide is commonly known as saccharine, a sweetener. The derivatives of this compound are biologically active (Primofiore et al., 1997) and used for the syntheses of various biologically active heterocyclic compounds. We report herein the crystal structure of the title compound, (I), as part of our ongoing studies on thiazine related heterocycles (Arshad et al., 2008).

The crystal structures of 3-methylbut-2-enyl)ammonium chloride, (II) (Kruszynski & Czestkowski, 2001), 2-(chloromethyl)-1,2-benzisothiazole-1,1,3(2H) -trione, (III) (Siddiqui et al., 2007) and 2-n-butyl-1,2-benziso- thiazol-3(2H)-one, (IV) (Yu et al., 2008) have been published.

In the molecule of (I) (Fig 1), the bond lengths (Allen et al., 1987) and angles are within normal ranges. Rings A (C1-C6) and B (S1/N1/C1/C6/C7) are, of course, planar and they are oriented at a dihedral angle of 2.91 (12)°. So, benzisothiazole ring system is nearly coplanar. The 3,3-dimethylallyl moiety C (C8-C12) is also planar with a maximum deviation of 0.0086 (16) Å for C10 atom, and it is oriented with respect to rings A and B at dihedral angles of A/C = 74.35 (7) and B/C = 71.86 (7) °. Atoms O1, O2 and O3 are 1.2007 (17), -1.2296 (19) and -0.0441 (27) Å away from the ring plane of B, respectively.

In the crystal structure, weak intermolecular C-H···O interactions (Table 1) link the molecules into chains along the c axis, in which they may be effective in the stabilization of the structure. There also exists a weak C—H···π interaction (Table 1).

Experimental top

For the preparation of the title compound, sodium salt of saccharine (1 g, 4.88 mmol) was dissolved in dimethylformamide (5 ml) in a round bottom flask (25 ml) equipped with condenser. Then, 3,3-dimethylallyl bromide (0.73 g, 4.88 mmol) was added to the solution and stirred at 353-373 K for 3 h. The progress of the reaction was observed by TLC. At completion of reaction, the mixture was poured on ice, precipitates obtained were filtered, washed with distilled water and dried. The residue was recrystalized in methanol to obtain the suitable crystals of the title compound.

Refinement top

H atoms were positioned geometrically, with C-H = 0.93, 0.97 and 0.96 Å for aromatic, methylene and methyl H, respectively, and constrained to ride on their parent atoms, with Uiso(H) = xUeq(C), where x = 1.5 for methyl H and x = 1.2 for all other H atoms.

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

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.
