In the title molecule, C17H12N4OS, the thiazole ring forms a dihedral angle of 10.8 (2)° with the phenyl ring and an angle of 3.1 (3)° with the indole ring system [which has a maximum deviation of 0.035 (2) Å]. The dihedral angle between the planes of the phenyl ring and the indole ring system is 11.5 (1)°. An intramolecular N—H⋯O hydrogen bond is observed. In the crystal, pairs of N—H⋯O hydrogen bonds form inversion dimers with an R22(8) graph-set motif.

An ethanolic solution of 1.81g (0.01 M) of 2-hydrazino-4-phenylthiazole was added drop wise to an etanolic solution of 1.47g (0.01 M) of isatin with constant stirring. After the complete addition, the reaction mixture was stirred further for 8-9 hrs until the solid separated out from the reaction mixture. The separated solid was filtered and washed with cold alcohol, dried and recrystallized from DMF (Yield: 95 %. MP: 443-446K). Block-shaped colourless crystals were obtained by slow evaporation of a solution of the title compound at room temperature in DMF:water in the ratio 2:1.
H atoms were placed in idealized positions and refined using a riding-model approximation with N—H = 0.86 Å, C—H = 0.93 Å and with Uiso(H) = 1.2Ueq(N,C).
Isatin derivatives and compounds containing a thiazole ring are class of organic compounds which have fascinated many synthetic researchers due to their wide range of biological activity ( Ali et al., 2011; Bharti et al., 2010; Kondratieva et al., 2007).
The molecular structure of the title compound is shown in Fig. 1. An intramolecular N—H···O hydrogen bond is observed. The thiazole ring is essentially planar with a maximum deviation of 0.005 (2) Å for atom N1. The thiazole ring (S1/C9/N1/C7/C8) forms dihedral angles of 10.8 (2)° with the phenyl ring (C1–C6) and 3.1 (3)° with the indole ring system (C10—C16/N4/C17, with a maximum deviation of 0.035 (2)Å for atom C17). The dihedral angle between the phenyl ring and the indole ring system is 11.5 (1)Å. In the crystal, pairs of N—H···O hydrogen bonds form inversion dimers (Fig. 2). A closely related structure appears in the literature (Sadik, et al., 2004).

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. |
