2-(2-Carb-oxy-eth-yl)-1,3-dioxoisoindoline-5,6-dicarb-oxy-lic acid methanol monosolvate.

ABSTRACT: In the title compound, C(13)H(9)NO(8)·CH(3)OH, the main mol-ecule possesses three carb-oxy-lic acid groups, which are asymmetrically distributed around the mol-ecule core. This results in hydrogen-bonding motifs ranging from a chain to various rings. The combination of the chain motif together with a carb-oxy-lic dimer R(2) (2)(8) ring motif creates a ribbon of mol-ecules propagating along the c-axis direction. A second ribbon results from the combination of the chain motif together with a methanol solvent mol-ecule and carboxyl-containing R(4) (4)(12) ring motif. These two ribbons combine alternately, forming a hydrogen-bonded layer of mol-ecules parallel to (2[Formula: see text]0).

5,6-Dimethyl-pyrazine-2,3-dicarb-oxy-lic acid.

Project description:The asymmetric unit of the title compound, C(8)H(8)N(2)O(4), consists of one complete mol-ecule and a second mol-ecule generated by the application of twofold axis. The mean planes of the two carboxyl groups attached to the pyrazine ring at neighboring positions are twisted by 10.8?(1) and 87.9?(1)° in the complete molecule and 43.0?(1)° in the symmetry-generated molecule. The crystal packing features O-H?N hydrogen bonds, which link the mol-ecules into layers along [101].

5-[(1H-Benzimidazol-1-yl)meth-yl]benzene-1,3-dicarb-oxy-lic acid.

Project description:Crystals of the title compound, C(16)H(12)N(2)O(4), were obtained accidentally from a hydro-thermal reaction of 5-[(1H-benzimidazol-1-yl)meth-yl]isophthalic acid with manganese bromide in the presence of N,N'-dimethyl-formamide. In the title mol-ecule, the benzimidazole ring system is almost planar, with a maximum deviation from the mean plane of 0.010 (2) Å. The benzimidazole and central benzene rings are inclined at a dihedral angle of 71.7 (6)°. The crystal structure is stabilized by O-H⋯N and O-H⋯O hydrogen bonds.

Benzene-1,3-dicarb-oxy-lic acid-1,2-bis-(4-pyrid-yl)ethene (1/1).

Project description:In the title compound, C(12)H(10)N(2)·C(8)H(6)O(4), the asymmetric unit contains two halves of 1,2-bis-(4-pyrid-yl)ethene (bpe) mol-ecules and one benzene-1,3-dicarb-oxy-lic acid (1,3-H(2)BDC) mol-ecule. These bpe and 1,3-H(2)BDC mol-ecules are linked by classical O-H⋯N hydrogen bonds, forming an extended one-dimensional zigzag chain. Each chain is further linked with neighboring ones by π-π inter-actions between the pyridine and aromatic rings [centroid-centroid distances = 3.9306 (15) Å] and the pyridine rings of pairs of symmetry-related mol-ecules [centroid-centroid distances = 3.5751 (15), 3.7350 (15) and 3.6882 (15) Å], with the formation of a three-dimensional supra-molecular framework.

Biphenyl-4,4'-dicarb-oxy-lic acid N,N-dimethyl-formamide monosolvate.

Project description:Biphenyl-4,4'-dicarb-oxy-lic acid was recrystallized from N,N-dimethyl-formamide (DMF) yielding the title compound, C(14)H(10)O(4)·2C(3)H(7)NO. The acid mol-ecules are located on crystallographic centres of inversion and are hydrogen bonded to DMF mol-ecules. These hydrogen-bonded units form infinite chains although there is no inter-action between the methyl groups of neighboring DMF mol-ecules.

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.

A monoclinic polymorph of 5-[(1H-benzimidazol-1-yl)meth-yl]benzene-1,3-dicarb-oxy-lic acid.

Project description:Crystals of the title compound, C(16)H(12)N(2)O(4), were obtained accidentally by the hydro-thermal reaction of 5-[(1H-benzo[d]imidazol-1-yl)meth-yl]isophthalic acid with manganese chloride tetra-hydrate in the presence of KOH as alkaline reagent for the deprotonation. A triclinic polymorph of this structure has been reported previously from a similar reaction [Cheng (2011 ?). Acta Cryst. E67, o3299]. The benzimidazole ring system is almost planar, with a maximum deviation from the mean plane of 0.020?(4)?Å. The benzimidazole unit and benzene ring are inclined at a dihedral angle of 68.17?(4)°, reflecting the axial rotation of the flexible benzimidazolyl arm. In the crystal, pairs of O-H?O hydrogen bonds link adjacent mol-ecules into inversion dimers. O-H?N contacts connect these dimers into zigzag chains along [010].

In the crystal, these units are connected into corrugated layers two mol-ecules thick and parallel to the ab plane by additional C-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.
