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

ABSTRACT: 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).

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). ...[more]

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].

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.

3-Carbamoyl-2,2-dimethyl-cyclo-pentane-1,1-dicarb-oxy-lic acid.

Project description:In the title compound, C(10)H(15)NO(5), the five-membered cyclo-pentane ring has an envelope conformation, with four atoms lying in a plane (mean deviation = 0.0213 Å), while the fifth atom deviates from this plane by 0.626 (2) Å. A three-dimensional structure is formed through N-H⋯O and O-H⋯O hydrogen bonds between the amide and carb-oxy-lic acid groups and both carb-oxy-lic acid and amide O-atom acceptors.

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 π-π 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.

e,e-trans-Cyclo-hexane-1,4-carb-oxy-lic acid-hexa-methyl-ene-tetra-mine (1/2).

Project description:The asymmetric unit of the title compound, 2C(6)H(12)N(4)·C(8)H(12)O(4), contains one half-mol-ecule of e,e-trans-cyclo-hexane-1,4-dicarb-oxy-lic acid (the complete molecule being generated by inversion symmetry) and one mol-ecule of hexa-methyl-ene-tetra-mine (HMTA), which are connected by O-H⋯N hydrogen bonds. This forms isolated trimers that pack in a herringbone fashion.

Project description: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.

(1S*,2S*,4R*,5R*)-Cyclo-hexane-1,2,4,5-tetra-carb-oxy-lic acid.

Project description:The title compound, C10H12O8, a prospective raw material for colourless polyimides which are applied to electronic and microelectronic devices, lies about an inversion centre and the cyclo-hexane ring adopts a chair conformation. Two crystallographycally independent carb-oxy-lic acid groups on adjacent C atoms are in equatorial positions, resulting in a mutually trans conformation. In the crystal, O-H?O hydrogen bonds around an inversion centre and a threefold rotoinversion axis, respectively, form an inversion dimer with an R 2 (2)(8) motif and a trimer with an R 3 (3)(12) motif.

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.

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.
