3-(1H-1,3-Benzimidazol-2-yl)-2,7-dimethoxyquinoline

Abstract

Key indicators: single-crystal X-ray study; T = 150 K; mean (C-C) = 0.002 Å; R factor = 0.046; wR factor = 0.112; data-to-parameter ratio = 16.2.In the title molecule, C 18 H 15 N 3 O 2 , the dihedral angle between the quinoline and benzimidazole ring systems is 23.57 (5) . The C atoms of the methoxy groups are both close to being coplanar with their attached ring systems [deviations = 0.193 (2) and À0.020 (2) Å ]. An intramolecular N-HÁ Á ÁO hydrogen bond closes an S(6) ring. In the crystal, N-HÁ Á ÁN hydrogen bonds link the molecules into C(4) chains propagating in [010]. Weak C-HÁ Á Á interactions also occur. Related literature ExperimentalCrystal data
