“…In addition benzimidazole and its derivatives are unidentate ligands and form complexes with metal ions through their tertiary Natom [2]. In the title crystal structure ,t he dihedral angles formed by the ring II (N3,C1,C2,C7,C8) and the ring III (C2,C3,C4,C5,C6,C7) was 0.5(3)°.The dihedral angles formed by the ring II and ring IV (C11,C12,C13,C14,C15,C16) with the ring I(N1,N2,C6 and C7) are 61.8 (8) …”

Source of materialAll commercially available reagents were used as supplied. 2-(bromomethyl)isoindoline-1,3-dione (4.8 g, 0.02 mol) and benzimidazole (2.4 g, 0.02 mol) were dissolved in 15ml chloroform. The solution was cooled to 283 K. Then, triethylamine (2.04 g, 0.02 mol) was added dropwise via cannula into the wellstirred solution at 283 K. The reaction mixture was stirred at 283 Kfor 7h.Then the solution was continued to stir at room temperature about 16 h. 20 ml water was added into the solution, the organic phase was seperated and dryed with anhydrous potassium carbonate,The colorless organic phase was evaporated. The title compound is afforded in 86 %yield. colorless crystals of suitable for X-ray determination were obtained from anhydrous ethanol at room temperature after two days. Chemical analysis -found: C, 68.98 %; H, 4.05 %; N, 15.16 %; calculated for C 16 H 11 N 3 O 2 :C, 69.29 %; H, 4.00 %; N, 15.16 %.
