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

ABSTRACT: 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].

Cyclo-hexane-1,4-dicarb-oxy-lic acid-pyridinium-4-olate (1/1).

Project description:In the title adduct, C5H5NO·C8H12O4, the heterocycle exists in its zwitterionic form. The cyclo-hexane ring exhibits a chair conformation with the carb-oxy-lic acid groups in equatorial and axial orientations. In the crystal, mol-ecules are linked through charge-assisted O-H?O(-), N(+)-H?O(-) and N(+)-H?O hydrogen bonds, and an additional series of C-H?O contacts, giving a pleated two-dimensional hydrogen-bonded network parallel to (-204).

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.

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.

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 ?-? 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.

Benzene-1,3,5-tri-carb-oxy-lic acid-pyridinium-2-olate (1/3).

Project description:The asymmetric unit of the title compound, C9H6O6·3C5H5NO, contains one benzene-1,3,5-tri-carb-oxy-lic acid mol-ecule (BTA) and three pyridin-2-ol mol-ecules each present in the zwitterion form. In the crystal, these entities are linked through O-H?O(-) and N(+)-H?O(-) hydrogen bonds, forming sheets parallel to (10-1). These layers contain macrocyclic rings of composition [BTA]2[pyol]6 and with graph-set notation R (6) 8(44), which are stacked along c through ?-? inter-actions [inter-centroid distances = 3.536?(2)-3.948?(3)?Å]. They are inter-connected by N(+)-H?O(-) hydrogen-bonded chains of pyridin-2-ol mol-ecules running parallel to c, forming a three-dimensional network. There are also C-H?O hydrogen bonds present which reinforce the three-dimensional structure.

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.

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.

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 crystal packing features O-H?N hydrogen bonds, which link the mol-ecules into layers along [101].

Bis(2-amino-pyridinium) 2,5-dicarb-oxy-benzene-1,4-dicarboxyl-ate.

Project description:In the title compound, 2C(5)H(7)N(2) (+)·C(10)H(4)O(8) (2-), the 2-amino-pyridinium (2-apyH) cation and 2,5-dicarb-oxy-benzene-1,4-dicarboxyl-ate (btcH2) anion are both nearly planar, with r.m.s. deviations of 0.015 and 0.050?Å, respectively. The angle between the latter least-squares planes is 17.68?(9)°. The overall crystal structure results from the packing of two-dimensional networks, formed by alternating 2-apyH and btcH2 linked by hydrogen bonds, parallel to (100).
