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

ABSTRACT: 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.

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].

2-Amino-5-chloro-pyridinium 3-carb-oxy-4-hy-droxy-benzene-sulfonate.

Project description:The asymmetric unit of the title salt, C(5)H(6)ClN(2) (+)·C(7)H(5)O(6)S(-), contains two independent 2-amino-5-chloro-pyridinium cations and two independent 3-carb-oxy-4-hy-droxy-benzene-sulfonate anions. In both anions, the O atoms of the sulfonate group are disordered over two sets of positions, with occupancy ratios of 0.47 (5):0.53 (5) and 0.50 (8):0.50 (8). In each anion, an intra-molecular O-H⋯O hydrogen bond generating an S(6) motif is observed. In the crystal structure, the cations and anions are linked via N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds, forming a two-dimensional network parallel to (110). The structure is further stabilized by π-π inter-actions between cations and anions [centroid-centroid distance = 3.5454 (12) Å]. The crystal studied was a non-merohedral twin, with a ratio of the twin components of 0.715 (3):0.285 (3).

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.

2-Amino-5-methyl-pyridinium 2-carb-oxy-benzoate.

Project description:In the title salt, C(6)H(9)N(2) (+)·C(8)H(5)O(4) (-), the hydrogen phthalate anion is essentially planar, with a maximum deviation of 0.011 (2) Å. In the crystal structure, the protonated N atom of the pyridine ring and the 2-amino group of the cation are hydrogen bonded to the carboxyl-ate O atoms of the anion via a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. In the hydrogen phthalate anion, there is a very strong, almost symmetric, intra-molecular O-H⋯O hydrogen bond, generating an S(7) motif [O⋯O = 2.382 (3) Å]. Furthermore, these two molecular motif rings are connected by a bifurcated N-H⋯(O,O) hydrogen-bonded motif R(1) (2)(4), forming a supra-molecular ribbon along the b axis. The crystal structure is further stabilized by π-π inter-actions between the cations and anions [centroid-centroid distance = 3.6999 (10) Å].

2-Amino-5-bromo-pyridinium 2-carb-oxy-benzoate.

Project description:The asymmetric unit of the title compound, C(5)H(6)BrN(2) (+)·C(8)H(5)O(4) (-), consists of two crystallographically independent 2-amino-5-bromo-pyridinium cations (A and B) and two 2-carb-oxy-benzoate anions (A and B). Each 2-amino-5-bromo-pyridinium cation is approximately planar, with a maximum deviation of 0.047 (1) Å in cation A and 0.027 (1) Å in cation B. The 2-amino-5-bromo-pyridinium unit in cation A is inclined at dihedral angles of 4.9 (3) and 2.2 (3)° with the phenyl rings of the A and B 2-carb-oxy-benzoate anions, respectively. The corresponding angles for cation B are 3.0 (3) and 5.6 (3)°. The mol-ecular structure is stabilized by an intra-molecular O-H⋯O hydrogen bond,which generates an S(7) ring motif. The cations and anions are linked via inter-molecular N-H⋯O and C-H⋯O hydrogen bonds, generating R(2) (2)(8) ring motifs. In the crystal packing, mol-ecules are linked into wave-like chains along [001] via adjacent ring motifs. Short inter-molecular distances between the phenyl and pyridine rings [3.613 (4) and 3.641 (4) Å] indicate the existence of π-π inter-actions. The crystal structure is a non-merohedral twin with a contribution of 0.271 (3) of the minor component.

2-Amino-6-methyl-pyridinium 2-carb-oxy-benzoate.

Project description:In the title mol-ecular salt, C(6)H(9)N(2) (+)·C(8)H(5)O(4) (-), an intra-molecular O-H⋯O hydrogen bond occurs within the anion, thereby generating an S(7) ring, which may correlate with the fact that both the carb-oxy-lic acid and carboxyl-ate groups are almost coplanar with their attached rings [dihedral angles = 2.9 (3) and 5.2 (3)°, respectively]. In the crystal, each cation is linked to its adjacent anion by two N-H⋯O hydrogen bonds; the dihedral angle between the pyridine and benzene rings is 2.22 (10)°. The ion pairs are linked by further N-H⋯O inter-actions.

Bis[4-amino-3,5-bis-(pyridin-2-yl)-4H-1,2,4-triazole-?N,N]bis-(benzene-1,2-dicarb-oxy-lic acid-?O)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 ?-? 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(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).
