1-Methyl-2-({[(1-methyl-1H-benzimid-azol-2-yl)meth-yl](phen-yl)amino}-meth-yl)1H-benzimidazol-3-ium picrate.

ABSTRACT: In the title molecular salt, C(24)H(24)N(5) (+)·C(6)H(2)N(3)O(7) (-), the dihedral angle between the benzimidazole rings of the cation is 5.041?(2)°. In the anion, the three nitro groups make dihedral angles of 2.468?(3), 12.795?(3) and 24.958?(4)° with respect to the central ring. In the crystal, weak aromatic ?-? stacking [centroid-centroid distance = 3.599?(15)?Å] consolidates the packing. In addition, an intra-molecular N-H?N hydrogen bond is observed.

In the title molecular salt, C(24)H(24)N(5) (+)·C(6)H(2)N(3)O(7) (-), the dihedral angle between the benzimidazole rings of the cation is 5.041 (2)°. In the anion, the three nitro groups make dihedral angles of 2.468 (3), 12.795 (3) and 24.958 (4)° with respect to the central ring. In the crystal, weak aromatic π-π stacking [centroid-centroid distance = 3.599 (15) Å] consolidates the packing. In addition, an intra-molecular N-H⋯N hydrogen bond is observed. ...[more]

2-Meth-oxy-6-(6-methyl-1H-benzimid-azol-2-yl)phenol.

Project description:In the title mol-ecule, C(15)H(14)N(2)O(2), the substituted benzene ring forms a dihedral angle of 4.15?(1)° with the benzimidazole ring system. An intra-molecular O-H?N hydrogen bond generates an S(6) ring motif. In the solid state, mol-ecules are linked into chains along the [001] via inter-molecular bifurcated N-H?(O,O) hydrogen bonds, which generate R(1) (2)(5) ring motifs. The crystal packing is also consolidated by C-H?? inter-actions, and ?-? stacking inter-actions between the imidazole and substituted benzene rings [centroid-centroid distance = 3.5746?(13)?Å]. The methyl group attached to the benzimidazole ring system is disordered over two positions with occupancies of 0.587?(6) and 0.413?(6), suggesting 180° rotational disorder for the benzimidazole group.

2-(2-Hy-droxy-3-meth-oxy-phen-yl)-1H-benzimidazol-3-ium perchlorate.

Project description:In the title mol-ecular salt, C(14)H(13)N(2)O(2) (+)·ClO(4) (-), the ring systems in the cation are almost coplanar [dihedral angle = 5.53?(13)°]. Intra-molecular N-H?O and O-H?O hydrogen bonds generate S(6) and S(5) rings, respectively. In the crystal, the two H atoms involved in the intra-molecular hydrogen bonds also participate in inter-molecular links to acceptor O atoms of the perchlorate anions. A simple inter-molecular N-H?O bond also occurs. Together, these form a double-chain structure along [101].

1-{[Dimeth-yl(phen-yl)sil-yl]meth-yl}-3-(2-phenyl-eth-yl)-1H-benzimidazol-3-ium bromide monohydrate.

Project description:The title compound, C(24)H(27)N(2)Si(+)·Br(-)·H(2)O, was synthesized from 1-(dimethyl-phenyl-silylmeth-yl)-1H-benzimidazole and (2-bromo-eth-yl)benzene in dimethyl-formamide.

In addition, the structure features π-π stacking inter-actions, with a face-to-face separation of 3.644 (3) Å between parallel benzimidazole ring systems.

2-(4-Methyl-sulfanylphen-yl)-1H-benzimidazol-3-ium bromide.

Project description:In the cation of the title compound, C(14)H(13)N(2)S(+)·Br(-), the essentially planar benzimidazole system (r.m.s. deviation = 0.0082 Å) is substituted with a 4-methyl-sulfanylphenyl ring. The dihedral angle between the benzimidazole system and the 4-methyl-sulfanylphenyl ring is 2.133 (2)°. The crystal structure is characterized by strong and highly directional inter-molecular N-H⋯Br hydrogen bonds involving the bromide ion. Moreover, C-H⋯S inter-actions result in chains of mol-ecules along the c axis. The supra-molecular assembly is further stabilized by π-π stacking inter-actions between the benzimidazole system and 4-methyl-sulfanylphenyl rings [centroid-centroid distance = 3.477 (4) Å].

Crystal structure of [3-(1H-benzimidazol-2-yl)propano-ato-κN (3)][3-(1H-benzimid-azol-2-yl)propanoic acid-κN (3)]copper(I).

Project description: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 crystal, O-H⋯O hydrogen bonds link the mol-ecules into chains along the a-axis direction. These chains are additionally linked into infinite two-dimensional networks in the ab plane by N-H⋯O hydrogen bonds.
