Benzimidazolium 3,5-dicarb-oxy-benzoate trihydrate.

ABSTRACT: Cocrystallization of benzimidazole with benzene 1,3,5-tricarb-oxy-lic acid in slightly basic medium afforded the title compound, C(7)H(7)N(2) (+)·C(9)H(5)O(6) (-)·3H(2)O, in which one of the imidazole N atom is protonated and one carb-oxy-lic group of aromatic acid is deprotonated. In the crystal structure, inter-molecular N-H⋯O hydrogen-bonding connects the two organic components into dimers, which are further linked into a three-dimensional network by O-H⋯O and N-H⋯O inter-actions between the water mol-ecules and the dimers.

4,4'-Bipyridine-pyridine-3,5-dicarb-oxy-lic acid (3/4).

Project description:In the title compound, 3C(10)H(8)N(2)·4C(7)H(5)NO(4), the asymmetric unit contains two mol-ecules of pyridine-3,5-dicarb-oxy-lic acid and one mol-ecule of 4,4'-bipyridine in general positions together with one mol-ecule of 4,4'-bipyridine lying across a centre of inversion, thus giving a 4:3 molar ratio of pyridine-3,5-dicarb-oxy-lic acid to 4,4'-bipyridine. The dihedral angle between the bipyridine rings on general positions is 21.2?(2)°. These mol-ecular units are linked by O-H?N hydrogen bonds forming an extended two-dimensional framework in the crystal.

4-Carbamoylpiperidinium 2-carb-oxy-benzoate-benzene-1,2-dicarb-oxy-lic acid (1/1).

Project description:The asymmetric unit of the title salt adduct, C(6)H(13)N(2)O(+)·C(8)H(5)O(4) (-)·C(8)H(6)O(4), comprises one isonipecotamide cation, a hydrogen phthalate anion and a phthalic acid adduct mol-ecule. These form a two-dimensional hydrogen-bonded network through head-to-tail cation-anion-adduct mol-ecule inter-actions which include a cyclic heteromolecular amide-carboxyl-ate motif [graph set R(2) (2)(8)], conjoint cyclic R(2) (2)(6) and R(3) (3)(10) piperidinium N-H⋯O(carbox-yl) associations, as well as strong carboxyl O-H⋯O(carbox-yl) hydrogen bonds.

2-[3-(1H-Benzimidazol-2-yl)prop-yl]-1H-benzimidazol-3-ium 3,5-dicarb-oxy-benzoate-benzene-1,3,5-tricarb-oxy-lic acid-water (1/1/1).

Project description:The title compound, C(17)H(17)N(4) (+)·C(9)H(5)O(6) (-)·C(9)H(6)O(6)·H(2)O, contains a protonated 2,2'-(1,3-propanedi-yl)bis-(1H-benzimidazole) cation, a deprotonated benzene-1,3,5-tricarb-oxy-lic acid anion, a neutral benzene-1,3,5-tricarb-oxy-lic acid mol-ecule and a water mol-ecule, which are linked together through N-H⋯O, O-H⋯O and weak C-H⋯O hydrogen bonds into almost double sheets parallel to (4). These hydrogen-bonded sheets are packed in the crystal with the formation of centrosymmetric voids of 25.5 Å(3), which are filled by the water mol-ecules.

Methyl 3,5-bis(cyclo-hexyl-meth-oxy)benzoate.

Project description:In the title compound, C22H32O4, the atoms of the methyl ester group and the alk-oxy O atoms are all coplanar with the central aromatic ring, with an r.m.s. deviation of 0.008 Å. Bonds to the methyl-ene and cyclo-hexyl groups are also very close to this plane, so that the mol-ecule is essentially flat, apart from the cyclo-hexyl groups. The mean planes through the cyclo-hexyl groups are tilted by 30.08 (9) and 36.14 (7)° with respect to the central aromatic ring. In the crystal, pairs of mol-ecules linked by C-H⋯O hydrogen bonds form planar units which are stacked along the a axis, with an average inter-planar distance of 3.549 (2) Å. Stacking appears to be stabilized by further weak C-H⋯O hydrogen bonds.

Bis[4-amino-3,5-bis-(pyridin-2-yl)-4H-1,2,4-triazole-κN,N]bis-(benzene-1,2-dicarb-oxy-lic acid-κO)copper(II) bis-(2-carb-oxy-benzoate).

Project description:In the complex cation of the title salt, [Cu(C(12)H(10)N(6))(2)(C(8)H(6)O(4))(2)](C(8)H(5)O(4))(2), the Cu(II) atom, lying on an inversion center, exhibits a distorted octa-hedral geometry defined by four N atoms from two 4-amino-3,5-bis-(pyridin-2-yl)-4H-1,2,4-triazole ligands in the equatorial plane and two axial O atoms from two benzene-1,2-dicarb-oxy-lic acid ligands. In the crystal, the complex cations and the monodeprotonated 2-carb-oxy-benzoate anions are connected by O-H⋯O and N-H⋯O hydrogen bonds, forming a tape along [100]. Adjacent tapes are further linked into a three-dimensional arrangement via π-π stacking inter-actions between the triazole and benzene rings and between the pyridine and benzene rings [centroid-centroid distances = 3.6734 (14)/3.9430 (16) and 3.8221 (14) Å]. Intra-molecular N-H⋯N and O-H⋯O hydrogen bonds are also observed.

Bis(benzimidazolium) naphthalene-1,5-disulfonate trihydrate.

Project description:The title compound, 2C(7)H(7)N(2) (+)·C(10)H(6)O(6)S(2) (2-)·3H(2)O, consists of two crystallographically independent benzimidazolium cations, two independent naphthalene-1,5-disulfonate dianions (both generated by inversion) and three water mol-ecules. These components construct an infinite three-dimensional framework in the crystal structure via O-H⋯O and N-H⋯O hydrogen bonds.

2-Amino-5-chloro-pyridinium 2-carb-oxy-benzoate-benzene-1,2-dicarb-oxy-lic acid (3/1).

Project description:The asymmetric unit of the title compound, 3C(5)H(6)ClN(2) (+)·3C(8)H(5)O(4) (-)·C(8)H(6)O(4), contains three independent 2-amino-5-chloro-pyridinium cations, three independent hydrogen phthal-ate anions and one phthalic acid mol-ecule. In the crystal structure, there are two kinds of supra-molecular tapes. One is formed by two independent cations with two anions through N-H⋯O and C-H⋯O hydrogen bonds. Another one is formed by the other cation and anion, and the phthalic acid mol-ecule via N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds. These two tapes are connected by an O-H⋯O hydrogen bond, forming a double-tape structure.

Methyl 3,5-bis-[(3-chloro-pyrazin-2-yl)-oxy]benzoate.

Project description:In the title compound, C16H10Cl2N4O4, the pyrazine rings make dihedral angles of 67.82 (9) and 75.91 (9)° with the benzene ring, while the dihedral angle between the pyrazine rings is 44.69 (10)°. The meth-oxy-carbonyl group makes a dihedral angle of 16.82 (8)° with the benzene ring to which it is attached. In the crystal, C-H⋯O hydrogen bonds link the mol-ecules, forming chains running along the ab plane.

2-Amino-5-methyl-pyridinium 2-hydr-oxy-3,5-dinitro-benzoate.

Project description:In the title mol-ecular salt, C(6)H(9)N(2) (+)·C(7)H(3)N(2)O(7) (-), the 2-amino-5-methyl-pyridinium cation is essentially planar, with a maximum deviation of 0.023 (1) Å. There is an intra-molecular O-H⋯O hydrogen bond in the 3,5-dinitro-salicylate anion, which generates an S(6) ring motif. In the crystal, the protonated N atom and the 2-amino group are hydrogen bonded to the carboxyl-ate O atoms via a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. Weak inter-molecular C-H⋯O inter-actions help to further stabilize the crystal structure.
