3-(1H-Benzimidazol-2-yl)-2-chloro-8-methylquinoline
Two independent mol-ecules of the title compound, C(17)H(12)ClN(3), are present in the structure. The angle between the planes defined by the atoms of the benzimidazole unit and the quinoline unit are 45.2 (3) and 44.0 (3)°, indicating an essentially identical conformation for both mol-ecules. Each of the independent mol-ecules is linked with a symmetry equivalent by an inter-molecular N-H⋯N hy...
متن کاملBis{2-[1-(8-hydroxy-2-quinolylmethyl)-1H-benzimidazol-2-yl]quinolin-8-ol} toluene solvate
Crystals of the title compound, 2C(26)H(18)N(4)O(2)·C(7)H(8), were obtained from the reaction of 8-hydroxy-quinoline with 1,2-phenyl-enediamine in methanol and recrystallized from toluene. The compound contains three essentially planar ring systems: the benzimidazole ring (r.m.s. deviation = 0.039 Å) and two 8-hydroxy-quinoline rings (r.m.s. deviations of 0.0056 Å in both rings). The benzimidaz...
متن کاملMethyl 2-(4a,8-Dimethyl-7-oxodecahydronaphthalen-2-yl)acrylate
The title compound, C(16)H(24)O(3), was isolated from the aerial part of Inula Viscosa- (L) Aiton [or Dittrichia Viscosa- (L) Greuter]. The mol-ecule contains two fused (trans) six-membered rings which both exibit a chair conformation. In the crystal, mol-ecules are linked into chains along [100] by weak C-H⋯O hydrogen bonds involving the methyl and carbonyl groups.
متن کامل2-(1H-Benzimidazol-2-yl)phenol
The title mol-ecule, C13H10N2O, is essentially planar, the maximum deviation from the plane of the non-H atoms being 0.016 (2) Å. The imidazole ring makes a dihedral angle of 0.37 (13)° with the attached benzene ring. An intra-molecular O-H⋯N hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked through N-H⋯O hydrogen bonds, forming chains propagating in [001]. The c...
متن کامل2-(1H-Benzimidazol-2-yl)-4-nitrophenol
The title compound, C(13)H(9)N(3)O(3), was prepared by the reaction of 5-nitro-salicyl-aldehyde with 1,2-diamino-benzene in methanol. The whole mol-ecule is approximately planar, with a mean deviation from the plane defined by the non-H atoms of 0.0311 (4) Å, and with a dihedral angle between the benzene ring and the benzimidazole ring system of 1.1 (3)°. An intra-molecular O-H⋯N hydrogen bond ...
