2-Amino-pyridinium trifluoro-acetate.

ABSTRACT: The asymmetric unit of the title compound, C(5)H(7)N(2) (+)·C(2)F(3)O(2) (-), contains four independent 2-amino-pyridinium cations and four independent trifluoro-acetate anions. In the crystal structure, these ions are linked by N-H?O hydrogen bonds, forming four cation-anion pairs each containing an R(2) (2)(8) ring motif. The ion pairs are linked into two independent chains along [100] by N-H?O hydrogen bonds. In addition, C-H?O and C-H?F hydrogen bonds and ??? inter-actions [centoid-centroid separation = 3.6007?(17)?Å] are observed.

Project description:The asymmetric unit of the title compound, C(6)H(9)N(2) (+)·C(2)F(3)O(2) (-), contains two independent 2-amino-4-methyl-pyridinium cations and two independent trifluoro-acetate anions.

2-Amino-4-methyl-pyridinium trifluoro-acetate: a monoclinic polymorph.

Project description:The title salt, C(6)H(9)N(2) (+)·C(2)F(3)O(2) (-), is a monoclinic polymorph of a previously reported structure [Hemamalini & Fun (2010). Acta Cryst. E66, o781-o782]. In the crystal structure, the cations and anions are linked by two different types of N-H⋯O hydrogen bonds, forming cation-anion pairs. These pairs are hydrogen bonded to neighbouring pairs via another N-H⋯O hydrogen bonds involving an H atom of the NH(2) group and one of the O atoms of the COO(-) group into a chain extended along the b axis.

2-Amino-5-nitro-pyridinium tri-fluoro-acetate.

Project description:The title salt, C5H6N3O2 (+)·C2F3O2 (-), crystallizes with two cations and two anions in the asymmetric unit. In the crystal, the acetate and pyridine groups are linked by a pair of N-H⋯O hydrogen bonds, forming loops described by the graph-set motif R 2 (2)(8). These loops are linked via N-H⋯O hydrogen bonds, forming chains along [001]. The chains are in turn linked by C-H⋯O and C-H⋯F hydrogen bonds, generating a three-dimensional supra-molecular network. In both anions, the O and F atoms are disordered over two sites, with occupancy ratios of 0.852 (3):0.148 (3) and 0.851 (3):0.149 (3).

3-Amino-carbonyl-pyridinium difluoro-acetate at 123?K.

Project description:In the crystal of the title compound, C(6)H(7)N(2)O(+)·C(2)HF(2)O(2) (-), the cation adopts a catemeric N-H?O hydrogen-bonded chain motif involving the carboxamide group, with two further N-H?O hydrogen bonds connecting the cations to adjacent difluoro-acetate anions via the carboxamide and pyridinium N atoms. The carboxamide group of the nicotinamidium ion is twisted by 32.3?(6)° from the pyridine ring plane. A number of C-H?O and C-H?F interactions consolidate the packing.

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.
