2-Methyl-5-nitro-1H-benzimidazol-6-amine dihydrate.

ABSTRACT: The title benzimidazole mol-ecule, C(8)H(8)N(4)O(2)·2H(2)O, is planar with a maximum deviation of 0.079?(2)?Å (for one of the O atoms in the nitro group). It crystallized as a dihydrate and inter-molecular O-H?O and N-H?O hydrogen bonds link the uncoordinated water mol-ecules, and the nitro and amine groups, respectively. In the crystal, N-H?O, O-H?N, O-H?O and C-H?O hydrogen bonds link the mol-ecules to form a three-dimensional network. A ?-? contact between the benzene rings, [centroid-centroid distance = 3.588?(1)?Å] may further stabilize the crystal structure.

It crystallized as a dihydrate and inter-molecular O-H⋯O and N-H⋯O hydrogen bonds link the uncoordinated water mol-ecules, and the nitro and amine groups, respectively. In the crystal, N-H⋯O, O-H⋯N, O-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules to form a three-dimensional network. A π-π contact between the benzene rings, [centroid-centroi ...[more]

Bis[bis-(1H-benzimidazol-2-ylmeth-yl)amine]copper(II) dichloride methanol disolvate dihydrate.

Project description:In the title compound, [Cu(C(16)H(14)N(5))(2)]Cl(2)·2CH(4)O·2H(2)O, the cationic metal complex resides on a crystallographic centre of inversion, with the Cu(2+) bonded to two bis-(1H-benzimidazol-2-ylmeth-yl)amines (IDB). The coordination geometry of the Cu(2+) ion is distorted octa-hedral with an N(6) ligand set. A three-dimensional framework structure is formed by means of hydrogen bonds and π-π inter-actions formed between imidazole and phenyl rings, and between phenyl and phenyl rings, with centroid-to-centroid distances of 3.690 (2)-3.977 (2) Å and interplanar spacings of 3.445 (2)-3.502 (2) Å.

Aqua(dimethylformamide){tris[(1-methyl-1H-benzimidazol-2-yl)methyl]amine}nickel(II) dipicrate.

Project description:In the title complex, [Ni(C(27)H(27)N(7))(C(3)H(7)NO)(H(2)O)](C(6)H(2)N(3)O(7))(2), the Ni(II) ion is coordinated in a slightly distorted octa-hedral coordination evironment by an NiN(4)O(2) ligand set. The tris-(N-methyl-benzimidazol-2-ylmeth-yl)amine ligand is in a tetra-dentate mode while a coordinated water molecule and a dimethyl-formamide ligand complete the coordination. In the crystal structure, inter-molecular O-H?O hydrogen bonds link the cation and one of the pictrate anions into four-component centrosymmetric clusters.

1-Prop-2-ynyl-1H-benzimidazol-2-amine.

Project description:In the title compound, C(10)H(9)N(3), the benzimidazol-2-amine and CH(2)-C CH units are not coplanar, with a dihedral angle of 60.36° between their mean planes. The crystal structure is stabilized by inter-molecular N-H⋯N hydrogen bonding and π-π inter-actions [centroid-centroid distances 3.677 (1) and 3.580 (1) Å], assembling the mol-ecules into a supra-molecular structure with a three-dimensional network.

2-(1H-Benzimidazol-2-yl)-4-nitro-phenol.

Project description:The title compound, C(13)H(9)N(3)O(3), was prepared by the reaction of 5-nitro-salicyl-aldehyde with 1,2-diamino-benzene in methanol. The whole mol-ecule is approximately planar, with a mean deviation from the plane defined by the non-H atoms of 0.0311 (4) Å, and with a dihedral angle between the benzene ring and the benzimidazole ring system of 1.1 (3)°. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, adjacent mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming centrosymmetric dimers.

Project description:The asymmetric unit of the title compound, (C(14)H(13)N(2)S)(2)[CuBr(4)]·2H(2)O, contains two cations, one anion and two solvent water mol-ecules that are connected via O-H?Br, N-H?Br and N-H?O hydrogen bonds into a two-dimensional polymeric structure. The cations are arranged in a head-to-tail fashion and form stacks along [100]. The central Cu(II) atom of the anion is in a distorted tetra-hedral environment.

2-Methyl-6-(6-methyl-1H-benzimidazol-2-yl)phenol-2-methyl-6-(5-methyl-1H-benzimidazol-2-yl)phenol (3/1).

Project description:The title compound, 0.75C(15)H(14)N(2)O·0.25C(15)H(14)N(2)O, is a co-crystal of 2-methyl-6-(6-methyl-1H-benzimidazol-2-yl)phenol as the major component and 2-methyl-6-(5-methyl-1H-benz-imidazol-2-yl)phenol as the minor component. The refined site-occupancy ratio is 0.746?(4)/0.254?(4). The conformations of both components are identical except for that of the methyl substituent on the benzene ring of the benzimidazole unit which is positionally disordered over two positions. The mol-ecule is essentially planar, the dihedral angle between the benzimidazole plane and the benzene ring being 3.49?(4)°. An intra-molecular O-H?N hydrogen bond generates an S(6) ring motif. In the crystal packing, mol-ecules are linked through N-H?O hydrogen bonds into chains along [201]. These chains are stacked approximately along the a-axis direction. The crystal packing is further stabilized by weak N-H?O and O?H?N hydrogen bonds, together with weak inter-molecular C-H?? inter-actions. A ?-? inter-action with a centroid-centroid distance of 3.6241?(6)?Å is also observed between the substituted phenyl ring and that of the benzimidazole system.

Bis[2-(1H-benzimidazol-2-yl)benzoato]copper(II) dihydrate.

Project description:In the title compound, [Cu(C(14)H(9)N(2)O(2))(2)]·2H(2)O, the Cu(II) ion lies on a centre of symmetry and is four-coordinated by two N atoms and two O atoms from two 2-(1H-benzimidazol-2-yl)benzoate ligands in a square-planar environment. The benzimidazol and benzyl rings form a dihedral angle of 42.8 (5)°. The mol-ecule contains two H-bonded carboxyl O acceptors and two H-bonded N-H donors in the benzimidazol groups, which inter-act with two symmetry-related uncoordinated water mol-ecules so that neighboring mol-ecular units are linked by (O-H)(water)⋯O(carbox-yl) hydrogen bonds with an R(2) (4)(8) graph-set motif, generating a helical chain in the a-axis direction. These chains are, in turn, inter-connected by (N-H)(benzimidazol)⋯O(water) hydrogen bonds, forming a three-dimensional supra-molecular network.

1-Allyl-5-nitro-1H-benzimidazol-2(3H)-one.

Project description:The benzimidazolone residue in the title mol-ecule, C10H9N3O3, is almost planar, with the largest deviation from the mean plane being 0.016?(2)?Å for the C atom linked to the nitro group. This plane is nearly perpendicular to the 1-allyl chain as indicated by the C-N-C-C torsion angle of 90.9?(3)°. The fused-ring system makes a dihedral angle of 5.6?(3)° with the nitro group, leading to a synperiplanar conformation. In the crystal, zigzag supra-molecular chains are formed along the a axis by N-H?O hydrogen bonds.

5-Nitro-1-nonyl-1H-benzimidazol-2(3H)-one.

Project description:In the title mol-ecule, C(16)H(23)N(3)O(3), the dihedral angle between the benzimidazole and nitro group planes is 5.34 (9)° and the dihedral angle between the benzimidazole and aliphatic chain mean planes is 73.23 (5)°. The C-C-C-C torsion angles (about 176°) of the nonyl group indicate an all-anti-periplanar conformation. In the crystal, adjacent mol-ecules are linked by pairs of N-H⋯O hydrogen bonds into inversion dimers. These mol-ecules are further connected through C-H⋯O inter-actions, building tapes parallel to (22).
