Abstract: The asymmetric unit of the crystal structure of the title compound, C23H19F3N2O, contains two independent molecules. In the two molecules the planar benzimidazole ring systems are oriented with respect to the phenyl/trifluoromethylbenzene rings at dihedral angles of 9.62 (6)/78.63 (7) and 2.53 (8)/83.83 (9)°. In the crystal structure, intermolecular C—H...N hydrogen bonds link the molecules into R22(6) dimers. The molecules are elongated along [001] and stacked along the b axis.

Abstract: In the title compound, C23H24F3N3O3, the morpholine ring adopts a chair conformation. The benzimidazole ring is approximately planar, with a maximum deviation of 0.028 (1) for one of the unsubstituted C atoms. The benzimidazole ring makes dihedral angles of 35.66 (4) and 75.45 (5)° with the attached phenyl and morpholine rings, respectively. In the crystal structure, adjacent molecules are linked via C—H...F and C—H...O hydrogen bonds to form a two-dimensional network.

Abstract: In the title molecule, C20H13F3N2, the benzimidazole unit is close to being planar [maximum deviation = 0.012 (1) ] and forms dihedral angles of 31.43 (7) and 61.45 (9)° with the 4-(trifluoromethyl)phenyl and 1-phenyl rings, respectively; the dihedral angle between these rings is 60.94 (10)°. In the crystal, C—H...F hydrogen bonds link the molecules into chains along the c-axis direction. The CF3 group is rotationally disordered with an occupancy ratio of 0.557 (8):0.443 (8) for the F atoms.

Acta Crystallographica Section E , 2013, DOI: 10.1107/s1600536813001220
Abstract: In the title compound, C14H9F3N2O, the best planes of the benzimidazole group and benzene ring form a dihedral angle of 26.68 (3)°. In the crystal, N—H...N hydrogen bonds link the molecules into infinite chains parallel to the c axis. Stacking interactions between the benzimidazole groups [centroid–centroid distance = 3.594 (5) ] assemble the molecules into layers parallel to (100). The trifluoromethyl group is disordered over three sets of sites with site-occupancy factors of 0.787 (4), 0.107 (7) and 0.106 (7).

Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808004510
Abstract: The asymmetric unit of the title compound, C20H16N2O, contains two molecules. The dihedral angles between the benzimidazole ring systems and the attached benzene rings are 10.6 (5) and 13.7 (5)°. The conformers are linked by bifurcated three-centre hydrogen bonds, forming chains along the diagonal of the ab plane. The packing is further stabilized by π–π and C—H...π interactions.

Abstract: The asymmetric unit of the title compound, C23H17F3N2O2, contains two molecules. In one of the molecules, the phenyl and triflouromethyl-substituted benzene rings form dihedral angles of 52.05 (8) and 33.70 (8)°, respectively, with the benzimidazole ring system, while the dihedral angle between them is 58.24 (10)°. The corresponding values in the other molecule are 58.40 (8), 25.90 (8) and 60.83 (10)°, respectively. In the crystal, molecules are linked into chains along [100] by C—H...O and C—H...N hydrogen bonds. Aromatic π–π stacking interactions [centroid–centroid distance = 3.6700 (12) ] also occur.

Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811029321
Abstract: In the title complex, [CdI2(C16H12N2O2)2], the CdII atom is located on a twofold rotation axis and is four-coordinated by two N atoms from symmetry-related 2-(2-furyl)-1-(2-furylmethyl)-1H-benzimidazole ligands and two I atoms in a distorted tetrahedral configuration. The benzimidazole rings in adjacent molecules are parallel, with an average interplanar distance of 3.486 . The I atom is disordered over two sites in a 0.85 (5):0.15 (5) ratio.

Abstract: The title compound, [ZnBr2(C11H13N3)], was synthesized by hydrothermal reaction of ZnBr2 and (S)-2-(pyrrolidin-2-yl)-1H-benzimidazole. The ZnII atom has a distorted tetrahedral geometry and is coordinated by two N atoms from the chelating organic ligand and two terminal Br anions. In the crystal structure, molecules are linked into a chain along the [101] direction by N—H...Br and C—H...Br hydrogen bonds.

Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808006454
Abstract: The title compound, [Cd(NO3)2(C11H13N3)2], was synthesized by hydrothermal reaction of Cd(NO3)2 and S-2-(pyrrolidin-2-yl)-1H-1,3-benzimidazole. The Cd atom lies on an inversion centre. The distorted octahedral 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 hydrogen bonds involving a nitrate O atom build up an infinite chain parallel to the a axis.

Abstract: In the molecule of the title compound, C22H18Cl2N2O, the planar benzimidazole ring system is oriented with respect to the phenyl and dichlorobenzene rings at dihedral angles of 12.73 (3) and 36.57 (4)°, respectively.
