Abstract top

In the title compound, C18H14N4O2, the triazole ring makes dihedral angles of 77.32 (8) and 75.56 (9)°, respectively, with the indoline residue and the terminal phenyl group. In the crystal, mol­ecules are linked by C-H...N hydrogen bonds into tapes parallel to the b axis. The tapes are linked together by [pi]-[pi] inter­actions between triazole rings [inter-­centroid distance = 3.4945 (9) Å].

Comment top

Isatin, 1H-indole-2,3-dione, is a heterocyclic compound of significant importance in medicinal chemistry. It is a synthetically versatile molecule, a precursor for a large number of pharmacologically active compounds. Isatin and its derivatives have aroused great attention in recent years due to their wide variety of biological activities, relevant to application as insecticides and fungicides and in a broad range of drug therapies, including anticancer drugs, antibiotics and antidepressants (Bhrigu et al., 2010; Da Silva et al., 2001; Ramachandran, 2011; Smitha et al., 2008). As a continuation of our research work devoted to the development of isatin derivatives (Qachchachi et al., 2013, 2014), we report in this paper the synthesis of a new indoline-2,3-dione derivative.

The molecule of title compound is build up from a fused five- and six-membered rings linked to a triazole ring which is connected to a benzyl ring as shown in Fig. 1. The indoline ring and the two carbonyl oxygen atoms are nearly coplanar, with the largest deviation from the mean plane being -0.059 (2) A° at O2 atom. The triazole plane is nearly perpendicular to the mean plane passing through the fused ring system (N1, C1 to C8) and to the terminal phenyl ring (C13 to C18) as indicated by the dihedral angles between them of 77.32 (8)° and 75.56 (9)°, respectively. The indazole system makes a dihedral angle of 77.02 (8)° with the phenyl ring.

In the crystal, the molecules are linked by C11–H11···N2 and C11–H11···N3 hydrogen bonds in the way to build bands parallel to the b axis direction. Two bands are linked together by ππ interactions between triazole rings [intercentroid distance = 3.494 Å] as shown in Fig. 2 and Table 1.

Experimental top

To a solution of 1-(prop-2-ynyl)indoline-2,3-dione (0.2 g, 2.4 mmol) dissolved in EtOH/H2O (1,1) was added 1-(azidomethyl)benzene (0.4 g, 4.1 mmol), in presence of CuSO4. The mixture was stirred for 24 h; the reaction was monitored by thin layer chromatography. The mixture was filtered and the solvent removed under vacuum. The solid obtained was recrystallized from ethanol to afford the title compound as yellow crystals in 81% yield.

Refinement top

All H atoms could be located in a difference Fourier map. Nevertheless, they were placed in calculated positions with C—H = 0.93 Å (aromatic), and C—H = 0.97 Å (methylene) and refined as riding on their parent atoms with Uiso(H) = 1.2 Ueq (aromatic and methylene).

Special details top

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 > 2σ(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.
