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...

In the title mol-ecule, C(16)H(23)N(3)O(3), the dihedral angle between the benzimidazole and nitro group planes is 5.34 (9)° and the dihedral angle between the benzimidazole and aliphatic chain mean planes is 73.23 (5)°. The C-C-C-C torsion angles (about 176°) of the nonyl group indicate an all-anti-periplanar conformation. In the crystal, adjacent mol-ecules are linked by pairs of N-H⋯O hydrog...

In the title compound, C(13)H(8)ClN(3)O(3)·C(3)H(7)NO, the benzimidazole and benzene rings make a dihedral angle of 0.63 (11)°. An intra-molecular O-H⋯N hydrogen bond generates an S(6) ring motif. The solvent mol-ecule is hydrogen-bonded to the benzimidazole mol-ecule by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds, generating an R(1) (2)(7) ring motif. In the crystal, the mol-ecules are arra...

A weak intra-molecular...

A dehydroabietyl derivative 2 bearing a 2-(2'-hydroxyphenyl)benzimidazole unit was synthesized and its sensing behaviors toward metal ions were investigated by UV-Vis and fluorescence spectroscopy methods. In THF solution, compound 2 exhibited excellent selectivity for CuII over miscellaneous other metal ions including CrII, MnII, CoII, NiII, ZnII, CdII, AlIII, MgII, PbII, HgII, NaI, LiI and KI...

In the mol-ecular structure of the title compound, C(21)H(18)N(2)O, the fused-ring system is essentially planar, the largest deviation from the mean plane being 0.0121 (9) Å. The O atom and adjacent C atom are located in Wyckoff position 4e on a twofold axis (0, y, 1/4). The two benzyl groups are almost perpendicular to the benzimidazole plane, but point in opposite directions. The dihedral ang...

Benzimidazole derivates play vital role in biological field such as antimicrobial, antiviral, antidiabetic, and anticancer activity. Therapeutic significance of these clinically useful drugs in treatment of microbial infections encouraged the development of some more potent and significant compounds. With the purpose of finding new chemical entities with enhanced antimicrobial activity, a serie...

In the title compound, C(25)H(21)BrN(2)O(3)·H(2)O, the benzimidazole fragment and the water mol-ecule of crystallization are each disordered over two sets of sites of equal occupancy. The dihedral angles between the least-squares planes of the benzimidazole and the 3-eth-oxy- and 4-bromo-benzene rings are 86.9 (6) and 85.1 (1)°, respectively in one disorder component. The crystal packing is sta...

In the title compound, [Cu(C10H9N2O2)(C10H10N2O2)], the Cu(I) ion is situated at a crystallographic centre of inversion and is coordinated in a linear environment by two benzimidazole N atoms from two symmetry-related 2-propanoic-1H-benzimidazole ligands. The ligands are disordered in a sense that statistically one of the carb-oxy-lic acid groups in each mol-ecule is deprotonated. In the crysta...

The title compound, [Cd(NO(3))(2)(C(11)H(13)N(3))(2)], was synthesized by hydro-thermal reaction of Cd(NO(3))(2) and S-2-(pyrrolidin-2-yl)-1H-1,3-benzimidazole. The Cd atom lies on an inversion centre. The distorted octa-hedral Cd environment contains two planar trans-related N,N-chelating S-2-(pyrrolidin-2-yl)-1H-1,3-benzimidazole ligands in one plane and two monodentate nitrate ligands. N-H⋯O...
