Biphenyl-3,3'-dicarb-oxy-lic acid.

ABSTRACT: The asymmetric unit of the title compound, C(14)H(10)O(4), contains one half mol-ecule, the complete mol-ecule being generated by a twofold axis. The two benzene rings form a dihedral angle of 43.11?(5)°. Inter-molecular O-H?O hydrogen bonds link the mol-ecules into one-dimensional zigzag chains. These chains are further connected into two-dimensional supra-molecular layers by weak ?-? stacking inter-actions between neighbouring benzene rings, with centroid-centroid distances of 3.7648?(8)?Å.

The asymmetric unit of the title compound, C(14)H(10)O(4), contains one half mol-ecule, the complete mol-ecule being generated by a twofold axis. The two benzene rings form a dihedral angle of 43.11 (5)°. Inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into one-dimensional zigzag chains. These chains are further connected into two-dimensional supra-molecular layers by weak π-π stacking inter-actions between neighbouring benzene rings, with centroid-centroid distances of 3.7648 (8) Å. ...[more]

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.

Hexaaqua-cobalt(II) 3,3'-dicarb-oxy-biphenyl-4,4'-dicarboxyl-ate.

Project description:In the crystal structure of the title compound, [Co(H(2)O)(6)](C(16)H(8)O(8)), both the cation and anion are centrosymmetric. The Co cation displays a CoO(6) octa-hedral geometry formed by six water mol-ecules. In the anion, the two carboxyl groups are oriented at dihedral angles of 4.8?(5) and 10.4?(7)° with respect to the benzene ring. Very strong O-H?O hydrogen bonds between the protonated and deprotonated carboxylate groups occur. Neighbouring cations and anions are connected through O-H?O hydrogen bonds into a three-dimensional supra-molecular structure.

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].

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.

Crystal structure and Hirshfeld surface analysis of 4,4'-di-meth-oxy-biphenyl-3,3',5,5'-tetra-carb-oxy-lic acid dihydrate.

Project description:In the crystal of the title compound, C18H14O10·2H2O, the arene rings of the biphenyl moiety are tilted at an angle of 24.3 (1)°, while the planes passing through the carboxyl groups are rotated at angles of 8.6 (1) and 7.7 (1)° out of the plane of the benzene ring to which they are attached. The crystal structure is essentially stabilized by O-H⋯O bonds. Here, the carboxyl groups of neighbouring host mol-ecules are connected by cyclic R 2 2(8) synthons, leading to the formation of a three-dimensional network. The water mol-ecules in turn form helical supra-molecular strands running in the direction of the crystallographic c-axis (chain-like water clusters). The second H atom of each water mol-ecule provides a link to a meth-oxy O atom of the host mol-ecule. A Hirshfeld surface analysis was performed to qu-antify the contributions of the different inter-molecular inter-actions, indicating that the most important contributions to the crystal packing are from H⋯O/O⋯H (37.0%), H⋯H (26.3%), H⋯C/C⋯H (18.5%) and C⋯O/O⋯C (9.5%) inter-actions.

Benzene-1,2-dicarb-oxy-lic acid-pyridinium-2-olate (1/1).

Project description:The asymmetric unit of the title compound, C(5)H(5)NO·C(8)H(6)O(4), contains one o-phthalate acid mol-ecule and one pyridin-2-ol mol-ecule, which exists in a zwitterionic form. In the o-phthalate acid mol-ecule, the carboxyl-ate groups are twisted from the benzene ring by dihedral angles of 13.6?(1)° and 73.1?(1)°; the hy-droxy H atom in the latter group is disordered over two positons in a 1:1 ratio. In the crystal, O-H?O and N-H?O hydrogen bonds link the mol-ecules into zigzag chains in [-101].

4,5-Dicarb-oxy-naphthalene-1,8-dicarb-oxy-lic anhydride-1,10-phenanthroline (1/1).

Project description:In the crystal structure of the title 1:1 adduct, C(12)H(8)N(2)·C(14)H(6)O(7), the carboxyl groups are involved in inter-molecular O-H⋯O hydrogen bonds, which link the mol-ecules into centrosymmetric dimers. These dimers are further linked by inter-molecular O-H⋯N hydrogen bonds. C-H⋯O inter-actions also occur between the 1,10-phenanthroline (phen) and 4,5-dicarb-oxy-naphthalene-1,8-dicarb-oxy-lic anhydride (H(2)NTC) mol-ecules. In addition, the crystal structure exhibits π-π inter-actions of the phen⋯phen and H(2)NTC⋯H(2)NTC types with centroid-centroid distances of 3.579 (3) and 3.774 (3) Å, respectively.

3,3'-[Biphenyl-4,4'-diylbis(-oxy)]diphthalic acid.

Project description:In the title mol-ecule, C(28)H(18)O(10), the two central benzene rings form a dihedral angle of 31.0?(1)°. In the phthalic acid fragments, the carb-oxy groups in the meta positions are approximately coplanar with the attached benzene rings, being inclined to their planes at 2.7?(1) and 10.3?(1)°, while the carb-oxy groups in the ortho positions are twisted from the benzene ring planes by 83.5?(1) and 75.4?(1)°. In the crystal, O-H?O hydrogen bonds link the mol-ecules into layers parallel to the bc plane. Weak C-H?O hydrogen bonds and ?-? inter-actions between the aromatic rings [centroid-centroid distance = 3.7674?(3)?Å] further consolidate the crystal packing.

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.

rac-cis-Cyclo-hexane-1,2-dicarb-oxy-lic acid-isoquinoline (1/1).

Project description:In the crystal structure of the title mol-ecular adduct, C(9)H(7)N·C(8)H(12)O(4), the two species are -linked through a carb-oxy-lic acid-isoquinoline O-H⋯N hydrogen bond. These mol-ecular pairs then inter-associate through the second acid group of the cis-cyclo-hexane-1,2-dicarb-oxy-lic acid molecules, forming a classic centrosymmetric cyclic head-to-head carb-oxy-lic acid-carboxyl O-H⋯O hydrogen-bonding association [graph-set R(2) (2)(8)], giving a zero-dimensional (cluster) structure, consisting of two of each species.
