2-Amino-5-chloro-pyridinium 2-carb-oxy-acetate.

ABSTRACT: The title salt, C(5)H(6)ClN(2) (+)·C(3)H(3)O(4) (-), contains two cations and two anions in the asymmetric unit. Both 2-amino-5-chloro-pyridinium ions are protonated at their pyridine N atoms and both hydrogen malonate ions feature an intra-molecular O-H?O hydrogen bond, which generates an S(6) ring motif and results in a folded conformation. In the crystal structure, the cations and anions are linked via N-H?O, O-H?O and C-H?O hydrogen bonds, forming chains propagating in [010], which are cross-linked by further C-H?O inter-actions.

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

Project description:In the title mol-ecular salt, C(6)H(9)N(2) (+)·C(3)H(3)O(4) (-), the cation is essentially planar, with a maximum deviation of 0.010?(3)?Å. In the anion, an intra-molecular O-H?O hydrogen bond generates an S(6) ring and results in a folded conformation. In the crystal, the protonated NH group 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. Weak inter-molecular C-H?O inter-actions help to further stabilize the crystal structure.

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 ?-? 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).

2-Amino-3-carb-oxy-pyridinium perchlorate.

Project description:The asymmetric unit includes two crystallographically independent equivalents of the title salt, C(6)H(7)N(2)O(2) (+)·ClO(4) (-). The cations and anions form separate layers alternating along the c axis, which are linked by N-H?O, O-H?O and C-H?O hydrogen bonds into a two-dimensional network parallel to (100). Further C-H?O contacts connect these layers, forming a three-dimensional network, in which R(4) (4)(20) rings and C(2) (2)(11) infinite chains can be identified.

2-Amino-5-chloro-pyridinium (Z)-3-carb-oxy-prop-2-enoate 0.25-hydrate.

Project description:In the title hydrated salt, C(5)H(6)ClN(2) (+)·C(4)H(3)O(4) (-)·0.25H(2)O, the water O atom lies on a twofold axis with 0.25 occupancy. The 2-amino-5-chloro-pyridinium cation is almost planar, with a maximum deviation of 0.015?(3)?Å. In the hydrogen malate anion, an intra-molecular O-H?O hydrogen bond generates an S(7) ring and results in a folded conformation. In the crystal, the protonated N atom 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. The ion pairs are further connected via O-H?O, N-H?O and C-H?O hydrogen bonds, forming layers parallel to the ab plane which stack down the c axis.

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.
