1,4-Bis(1H-benzimidazol-1-yl)but-2-ene
In the pseudo-centrosymmetric mol-ecule of the title compound, C(18)H(16)N(4), two benzimidazole fragments form the dihedral angles of 83.49 (7) and 79.37 (7)°, with the mean plane of the linking butene chain. No classical inter-molecular inter-actions are observed. The porous crystal packing exhibits voids of 85 Å(3).

In the title compound, C(10)H(12)N(2)OS, the asymmetric unit consists of two independent mol-ecules. In the crystal structure, mol-ecules form R(4) (4)(28) centrosymmetric tetra-mers via O-H⋯N hydrogen bonds. These tetra-mers are stacked along the c axis via C-H⋯O hydrogen bonds. C-H⋯π and π-π inter-actions are also present; in the latter, the centroid-centroid distances are 4.075 (1) and 3.719...

In the mol-ecule of the title compound, C(15)H(12)N(2)O, the planar benzimidazole system is oriented at a dihedral angle of 80.43 (5)° with respect to the phenyl ring. In the crystal structure, non-classical inter-molecular C-H⋯N and C-H⋯O hydrogen bonds link the mol-ecules into layers parallel to the ab plane.

In the title salt, C(18)H(19)N(4)O(+)·PF(6) (-), the dihedral angle between the benzimidazolium and benzimidazole ring systems is 16.24 (2)°. In the cation, a π-π inter-action is observed between the imidazolium ring and the benzene ring of the benzimidazole ring system [centroid-centroid distance = 3.5713 (11) Å]. The PF(6) (-) ion is disordered over two sites, with occupancies of 0.895 (2) an...
متن کامل1-Benzyl-1H-benzimidazol-2(3H)-one
The fused five- and six-membered rings in the title compound, C(14)H(12)N(2)O, are essentially planar, the largest deviation from the mean plane being 0.023 (2) Å. The dihedral angle between the benzimidazole mean plane and the phenyl ring is 68.50 (6)°. In the crystal, each mol-ecule is linked to its symmetry equivalent created by a crystallographic inversion center by pairs of N-H⋯O hydrogen ...
