The title compound [systematic name: 2-(1H-1,2,3-benzotriazol-1-ylmethyl)isoindole-1,3-dione], C15H10N4O2, was prepared by the reaction of 1H-benzotriazole and 2-bromomethylisoindole-1,3-dione. The benzotriazole and isoindole units are almost planar and make a dihedral angle of 70.2 (1)° (mean planes include C and N atoms). A weak C—H⋯O intramolecular hydrogen bond involving a carbonyl O atom as acceptor stabilizes the observed molecular conformation.

The title compound was synthesized with the following procedure: 2-bromomethyl-isoindole-1,3-dione (3.6 g, 0.015 mol) and 1H-benzotriazole (1.78 g, 0.015 mol) were dissolved in chloroform (15 ml). The solution was cooled to 283 K. Then, 1.5 g (0.015 mol) of triethylamine was added dropwise via a cannula into the well stirred solution, at 283 K. The reaction mixture was stirred at 283 K for 6 h. and at room temperature for an additional time of 16 h. Water (20 ml) was added into the solution and the resulting white solid was filtered. The organic phase was separated and dried with anhydrous potassium carbonate. The colourless organic phase was evaporated, affording (I), in 53% yield. Crystals suitable for X-ray studies were obtained from anhydrous acetone, at room temperature, after three days.
All H atoms were placed geometrically (C—H = 0.93 Å for aromatic CH, 0.97 Å for methylene CH2), and refined as riding to their parent atom with Uiso(H) = 1.2Ueq(C).

1H-Benzotriazole and its derivatives exhibit a broad spectrum of pharmacological activities, such as antifungal, antitumor and antineoplastic activities (Chen & Wu, 2005; Jiao et al., 2005). We report here the synthesis and structure of the title compound, (I), as part of our ongoing studies on new benzotriazole compounds with higher bioactivity.
In the molecular structure of (I), bond lengths and angles are within normal ranges (Fig. 1). The dihedral angle formed by the ring 1 (N1/N2/N3/C1/C6) and the ring 3 (C1/C2/C3/C4/C5/C6) is 1.4 (1)°. The dihedral angles formed by the rings 1 and 4 (C9/C10/C11/C12/C13/C14) with the ring 2 (N4/C8/C9/C14/C15) are 69.7 (3) and 1.0 (8)°, respectively. In the phthalimide group, the C?O bond lengths are 1.201 (2) and 1.2013 (19) Å, and the C—N bond lengths are 1.400 (2) and 1.395 (2) Å. There is a C—H···O intramolecular interaction (Table 2) stabilizing the observed molecular conformation.
