2-Amino-6-methyl-pyridinium 2,2,2-tri-chloro-acetate.

ABSTRACT: In the asymmetric unit of the title mol-ecular salt, C6H9N2 (+)·C2Cl3O2 (-), there are two independent 2-amino-6-methyl-pyridinium cations and two independent tri-chloro-acetate anions. The pyridine N atom of the 2-amino-6-methyl-pyridine mol-ecule is protonated and the geometries of these cations reveal amine-imine tautomerism. Both protonated 2-amino-6-methyl-pyridinium cations are essentially planar [maximum deviations = 0.026?(2) and 0.012?(2)?Å]. 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. These motifs are connected via N-H?O and C-H?O hydrogen bonds to form slabs parallel to (101).

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).

N-(4-Chloro-phenyl-sulfon-yl)-2,2,2-tri-methyl-acetamide.

Project description:In the crystal structure of the title compound (N4CPSTMAA), C(11)H(14)ClNO(3)S, the conformations of the N-H and C=O bonds in the amide group are anti to each other, similar to those observed in N-phenyl-sulfonyl-2,2,2-trimethyl-acetamide (NPSTMAA) and 2,2,2-trimethyl-N-(4-methyl-phenyl-sulfon-yl)acetamide (N4MPSTMAA). The bond parameters in N4CPSTMAA are similar to those in NPSTMAA, N4MPSTMAA, N-aryl-2,2,2-trimethyl-acetamides and 4-chloro-benzene-sulfonamide. The -SNHCOC- unit including the amide group is essentially planar and makes a dihedral angle of 82.2?(1)° with the benzene ring, comparable to the values of 79.1?(1) and 71.2?(1)° in NPSTMAA and N4MPSTMAA, respectively. The mol-ecules in N4CPSTMAA are linked into a chain by inter-molecular N-H?O hydrogen bonds.

2-Amino-4-methyl-pyridinium trifluoro-acetate.

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.

In the crystal, the cations and anions are linked into chains along the b axis by N-H?O hydrogen bonds and these chains are cross-linked by C-H?O hydrogen bonds, forming a two-dimensional network lying parallel to (101). The crystal structure is further stabilized by ?-? inter-actions between the pyridinium rings [centroid-centroid distances = 3.5842?(13) and 3.5665?(16)?Å].
