Glutaric acid-2-(pyridin-4-yl)-1H-benzimidazole (1/1).

ABSTRACT: The crystal structure of the title co-crystal, C(12)H(9)N(3)·C(5)H(8)O(4), N-H⋯O and O-H⋯N hydrogen bonds link the components. There are also π-π stacking inter-actions between the imidazole rings, between the imidazole and pyridine rings and between the pyridine and benzene rings [centroid-centroid distances = 3.643 (2), 3.573 (2) and 3.740 (1)Å, respectively].

2-(Pyridin-4-yl)-1H-benzimidazole.

Project description:The title compound, C12H9N3, is an unhydrated analogue of the previously reported trihydrate. The mol-ecule is essentially planar, with a 3.62?(11)° angle between the pyridine and benzimidazole planes. In the crystal, N-H?N hydrogen bonds result in chains of mol-ecules parallel to [010], which are additionally linked by weak ?-? stacking inter-actions [centroid-centroid distance = 3.7469?(17)?Å], resulting in extended sheets of molecules parallel to (103).

1,1'-(Butane-1,4-di-yl)bis-[2-(pyridin-2-yl)-1H-benzimidazole].

Project description:The complete mol-ecule of the title compound, C(28)H(24)N(6), is generated by inversion symmetry with the inversion centre located at the mid-point of the central C-C bond of the butanediyl unit. The benzimidazole and pyridine rings are almost coplanar, the dihedral angle between their mean planes being 6.86?(11)°.

5,6-Dimethyl-2-(pyridin-2-yl)-1-[(pyri-din-2-yl)meth-yl]-1H-benzimidazole.

Project description:The title compound, C20H18N4, was obtained via the condensation of 4,5-di-methyl-benzene-1,2-di-amine with pyridine-2-carbaldehyde. The plane of the 2-(pyridin-2-yl) substitutent is canted by 2.75?(11)° from the plane of the benzimidazole system. The mol-ecule exhibits an S(6) C-H?N intra-molecular hydrogen-bond motif. In the crystal, C-H?N hydrogen bonds link pairs of mol-ecules related by a crystallographic inversion center, forming R 2 (2)(20) rings. Additional weak C-H?N hydrogen bonds result in C(9) chains parallel to [001].

(R)-(+)-2-{[(3-Methyl-4-nitro-pyridin-2-yl)meth-yl]sulfin-yl}-1H-benzimidazole.

Project description:The title compound, C(14)H(12)N(4)O(3)S, is an inter-mediate of Dexlansoprazole, a proton pump inhibitor (PPI) mainly developed for anti-ulcer activity. The absolute configuration of the title compound was determined as R. The crystal structure reveals that the mol-ecules form chains along the b axis through N-H?N and C-H?O hydrogen-bonded dimers. These chains are connected via weak C-H?O hydrogen bonds.

1-(4-Fluoro-benz-yl)-2-(pyridin-2-yl)-1H-benzimidazole.

Project description:In the title compound, C19H14FN3, the dihedral angles between the benzimidazole unit (r.m.s. deviation= 0.017?Å) and the pyridine and benzene rings are 24.46?(4) and 81.87?(3)°, respectively. In the crystal, mol-ecules are stacked along the a-axis direction by C-H?? inter-actions.

Hexa-?-chlorido-?(4)-oxido-tetra-kis-({1-[(pyridin-2-yl)meth-yl]-1H-benzimidazole-?N}copper(II)).

Project description:The title tetra-nuclear complex, [Cu(4)Cl(6)O(C(13)H(11)N(3))(4)], features a tetra-hedral arrangement of copper(II) ions bonded to the central O atom (site symmetry [Formula: see text]). Each of the six edges of the Cu(4) tetra-hedron is bridged by a chloride ion (one of which has site symmetry 2), so that each copper ion is linked to the other three metal ions through the central O atom and through three separate chloride-ion bridges. The fifth coord-ination position, located on the central Cu-O axis on the outside of the cluster, is occupied by an N atom of the mono-dentate 1-(pyridin-2-ylmeth-yl)-1H-benzimidazole ligand. The resulting coordination geometry of the metal ion is a distorted trigonal bipyramid with the O and N atoms in the axial positions. The dihedral angle between the benzimidazole ring system and the pendant pyridine ring is 61.0?(2)°.

2-{[3-Methyl-4-(2,2,2-trifluoro-eth-oxy)pyridin-2-yl]methyl-sulfan-yl}-1H-benzimidazole monohydrate.

Project description:The asymmetric unit of the title compound, C(16)H(14)F(3)N(3)OS·H(2)O, contains two independent mol-ecules (A and B) and two water mol-ecules, one of which is disordered over two positions in a 0.790?(8):0.210?(8) ratio. The mol-ecular conformations are close, the benzimidazole mean plane and pyridine ring forming dihedral angles of 1.8?(3) and 0.1?(2)° in mol-ecules A and B, respectively. The water mol-ecules are involved in formation of two independent hydrogen-bonded chains via N-H?O and O-H?N hydrogen bonds. Chains propagating along the a axis are formed by mol-ecule A and one independent water mol-ecule, while chains propagating along the b axis are formed by mol-ecule B and the other independent water mol-ecule. The crystal packing exhibits ?-? inter-actions, as indicated by short distances of 3.607?(3) and 3.701?(3)?Å between the centroids of the imidazole and pyridine rings of neighbouring mol-ecules.

Ethyl 2-[5-(4-fluoro-phen-yl)pyridin-3-yl]-1-[3-(2-oxopyrrolidin-1-yl)prop-yl]-1H-benzimidazole-5-carboxyl-ate.

Project description:In the title compound, C28H27FN4O3·H2O, the benzimidazole ring system is essentially planar with a maximum deviation of 0.028?(1)?Å. It makes dihedral angles of 47.59?(5) and 60.31?(5)°, respectively, with the pyridine and benzene rings, which make a dihedral angle of 22.58?(6)° with each other. The pyrrolidine ring shows an envelope conformation with one of the methyl-ene C atoms as the flap. In the crystal, the components are connected into a tape along the b-axis direction through O-H?O and O-H?N hydrogen bonds and a ?-? inter-action between the pyridine and benzene rings [centroid-centroid distance of 3.685?(8)?Å]. The tapes are further linked into layers parallel to the ab plane by C-H?O and C-H?F inter-actions.

2-[4-(1H-1,2,4-Triazol-1-yl)phen-yl]-1H-benzimidazole.

Project description:In the title compound, C(15)H(11)N(5), the benzimidazole ring system is nearly planar [maximum deviation = 0.039?(2)?Å], and is oriented at a dihedral angle of 28.85?(10)° with respect to the benzene ring; the dihedral angle between the triazole and benzene rings is 17.30?(15)°. In the crystal N-H?N hydrogen bonds link the mol-ecules into chains. Weak C-H?N inter-actions are also present.
