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

ABSTRACT: 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].

5,6-Dimethyl-2-(5-methyl-thio-phen-2-yl)-1-[(5-methyl-thio-phen-2-yl)meth-yl]-1H-benzimidazole.

Project description:The title mol-ecule, C20H20N2S2, is T-shaped and consists of a nearly flat 5,6-dimethyl-2-(5-methyl-thio-phen-2-yl)benzimidazole system approximately perpendicular to the 5-methyl-thio-phen-2-ylmethyl substituent. The 5,6-dimethyl-2-(5-meth-yl-thio-phen-2-yl)benzimidazole system is rotationally disordered about the two imidazole N atoms as approximated by a twofold rotation axis with a refined major/minor occupancy ratio of 0.884 (2):0.116 (2). The benzimidazole ring system is essentially planar, the largest deviations being 0.026 (2) and 0.044 (18) Å in the major and minor components, respectively. The inter-planar angles between the benzimidazole unit and the 5-methyl-thio-phen-2-yl substituent are 10.8 (3) and 8(3)° in the major and minor components, respectively, and the corresponding angles with the 5-methyl-thio-phen-2-ylmethyl substituent are 88.12 (8) and 89.5 (4)°. In the crystal, mol-ecules are oriented with their 2-(5-methyl-thio-phen-2-yl)benzimidazole mean planes approximately parallel to (11[Formula: see text]) and appear to be held together by π-π [2-thiophene⋯imidazole centroid-centroid distance = 4.1383 (7) Å] and C-H⋯π contacts. A weak C-H⋯N hydrogen bond generates infinite chains parallel to [100].

Project description:The title compound, C18H13Br3N2S2, was obtained via the reaction of N-bromo-succinamide with 5,6-dimethyl-2-(thio-phen-2-yl)-1-[(thio-phen-2-yl)meth-yl]-1H-benzimidazole.

The 5-bromo-thio-phen-2-yl mean plane is canted to the benzimidazole plane by 20.0 (4) and 21 (4)° in the major and minor components, respectively. In the crystal, weak C-H⋯N inter-actions link the mol-ecules into infinite C(7) chains along the 21 axes.

(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.

Project description:The asymmetric unit of the title compound, [Zn(C18H12N5)2(H2O)2], consists a Zn(II) ion, located on an inversion center, a deprotonated 5-pyridin-2-yl-3-[4-(pyridin-4-yl)phen-yl]-1H-1,2,4-triazol-1-ido ligand and a water mol-ecule. The whole mol-ecule is generated by inversion symmetry. The Zn(II) ion has a distorted octa-hedral coordination geometry, defined by four N atoms from the two deprotonated organic ligands and two water O atoms. In the crystal, O-H⋯N hydrogen bonds link the mol-ecules, forming a three-dimensional network.

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)°.
