In the title compound, C16H13N5O3S·CH4O, the dihedral angle between the isatin unit and the 2-methylphenyl group is 41.81 (2)° and intramolecular N—H⋯O and N—H⋯N hydrogen bonds occur, generating S(6) and S(5) rings, respectively. In the crystal, polymeric chains arise as a result of N—H⋯O, O—H⋯S and C—H⋯O interactions.

4-o-Tolylthiosemicarbazide (0.45 g, 2.5 mmol) dissolved in ethanol (10 ml) was added to a hot solution of 5-nitroisatin (0.46 g, 2.5 mmol) in 50% aqueous ethanol (30 ml) containing a few drops of glacial acetic acid. The reaction mixture was then refluxed for 2 h. The yellow crystalline solid formed during heating under reflux was collected by suction filtration. Thorough washing with hot aqueous ethanol furnished the title compound (I) in pure form (0.71 g, 80%), m.p. 499 K. The yellow needles of (I) were grown in ethanol:n-hexane (1:4) system at room temperature by diffusion method.
The H-atoms were positioned geometrically (O–H = 0.82 Å, N–H = 0.86 Å, C–H = 0.93–0.96 Å) and refined as riding with Uiso(H) = 1.2Ueq(carrier) or 1.5Ueq(methyl C).
Recently we have reported the preparation and
of (Z)-4-Hexyl-1-(5-nitro-2-oxo-2,3-dihydro-1H-indol-3-ylidene) thiosemicarbazide (Pervez et al., 2009). The title compound (I, Fig. 1) has been prepared and being reported in continuation of synthesizing various isatin derivatives due to their importance.The β-4-(p-tolyl)thiosemicarbazone (Revenko et al., 1994) has been published. The title compound (I) differs from (II) due to attachment of NO2 group with isatin and positional change of CH3 group on the benzene ring.
of (II) IsatinIn the
of (I), the group A (C1—C8/N1/N2/N3/O1) of isatin moiety and 2-methylphenyl group B (C10–C17) are planar with a maximum r. m. s. deviations of 0.0187 and 0.0065 Å respectively, from their mean square plane. The dihedral angle between A/B is 41.81 (2)°. The nitro group C (N2/O2/O3) is oriented at a dihedral angle of 5.7 (2)° with group A. In (I), there exist two interamolecular H-bondings resulting in S(5) and S(6) ring motifs (Bernstein et al., 1995). Methanol monosolvate interlinks the molecules through H-bondings (Table 1., Fig. 2). The molecules are stabilized in the form of infinite one dimensional polymeric chains.For related structures, see: Revenko et al. (1994); Pervez et al. (2009).

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. |

Recently we have reported the preparation and crystal structure of (Z)-4-Hexyl-1-(5-nitro-2-oxo-2,3-dihydro-1H-indol-3-ylidene) thiosemicarbazide (Pervez et al., 2009). The title compound (I, Fig. 1) has been prepared and being reported in continuation of synthesizing various isatin derivatives due to their importance.
The crystal structure of (II) Isatin β-4-(p-tolyl)thiosemicarbazone (Revenko et al., 1994) has been published. The title compound (I) differs from (II) due to attachment of NO2 group with isatin and positional change of CH3 group on the benzene ring.
In the crystal structure of (I), the group A (C1—C8/N1/N2/N3/O1) of isatin moiety and 2-methylphenyl group B (C10–C17) are planar with a maximum r. m. s. deviations of 0.0187 and 0.0065 Å respectively, from their mean square plane. The dihedral angle between A/B is 41.81 (2)°. The nitro group C (N2/O2/O3) is oriented at a dihedral angle of 5.7 (2)° with group A. In (I), there exist two interamolecular H-bondings resulting in S(5) and S(6) ring motifs (Bernstein et al., 1995). Methanol monosolvate interlinks the molecules through H-bondings (Table 1., Fig. 2). The molecules are stabilized in the form of infinite one dimensional polymeric chains.
