Crystal structure of 2-amino-pyridinium 6-chloro-nicotinate.

ABSTRACT: In the title salt, C5H7N(+)·C6H3ClNO(-), the 2-amino-pyri-din-ium cation inter-acts with the carboxyl-ate group of the 6-chloro-nicotinate anion through a pair of independent N-H?O hydrogen bonds, forming an R 2 (2)(8) ring motif. In the crystal, these dimeric units are connected further via N-H?O hydrogen bonds, forming chains along [001]. In addition, weak C-H?N and C-H?O hydrogen bonds, together with weak ?-? inter-actions, with centroid-centroid distances of 3.6560?(5) and 3.6295?(5)?Å, connect the chains, forming a two-dimensional network parallel to (100).

In the title salt, C5H7N(+)·C6H3ClNO(-), the 2-amino-pyri-din-ium cation inter-acts with the carboxyl-ate group of the 6-chloro-nicotinate anion through a pair of independent N-H⋯O hydrogen bonds, forming an R 2 (2)(8) ring motif. In the crystal, these dimeric units are connected further via N-H⋯O hydrogen bonds, forming chains along [001]. In addition, weak C-H⋯N and C-H⋯O hydrogen bonds, together with weak π-π inter-actions, with centroid-centroid distances of 3.6560 (5) and 3.6295 (5) Å, conn ...[more]

Crystal structure of bis-(2-amino-5-chloro-pyridinium) tetra-chlorido-cobaltate(II).

Project description:The title salt, (C5H6ClN2)2[CoCl4], was synthesized by slow evaporation of an aqueous solution at room temperature. The asymmetric unit consists of two essentially planar (C5H6ClN2)(+) cations [maximum deviations = 0.010?(3) and 0.014?(3)?Å] that are nearly perpendicular to each other [dihedral angle = 84.12?(7)°]. They are bonded through N-H?Cl hydrogen bonds to distorted [CoCl4](2-) tetra-hedra, leading to the formation of undulating layers parallel to (100). The structure is isotypic with the Zn analogue [Kefi et. al (2011). Acta Cryst. E67, m355-m356.].

Crystal structure of 2,6-di-amino-pyridinium chloride.

Project description:The asymmetric unit of the title salt, C5H8N3 (+)·Cl(-), comprises one half of the 2,6-di-amino-pyridinium cation (the other half being completed by the application of mirror symmetry) and one Cl(-) counter-anion, also located on the mirror plane. The amino N atom shows a significant pyramidalization, with a dihedral angle of 30.4 (14)° between the least-squares planes of the amino group and the non-H atoms of the 2,6-di-amino-pyridinium moiety. In the crystal, the cationic mol-ecules and Cl(-) counter-anions are arranged in sheets parallel to (001) consisting of alternating polar and non-polar parts associated with the the Cl(-) anions, pyridinium and amino moieties, and the pyridine rings, respectively. N-H⋯Cl inter-actions within the polar part, as well as slipped π-π inter-actions in the non-polar part, help to establish the three-dimensional network.

Crystal structure of 3-amino-1-propyl-pyridinium bromide.

Project description:The title mol-ecular salt, C8H13N2 (+)·Br(-), crystallizes with two independent 3-amino-pyridinium cations and two bromide anions in the asymmetric unit (Z' = 2). In the pyridine ring, the N atom is alkyl-ated by a propyl group. The dihedral angle between the mean planes of the pyridinium ring and the propyl group is 84.84?(2)° in cation A, whereas the corresponding angle is 89.23?(2)° in cation B. In the crystal, the anions and cations are linked via N-H?Br and C-H?Br hydrogen bonds, forming chains propagating along [100].

Crystal structure of 2-amino-5-nitro-pyridinium sulfamate.

Project description:The title mol-ecular salt, C5H6N3O2 (+) ·H2NO3S(-), was obtained from the reaction of sulfamic acid with 2-amino-5-nitro-pyridine. A proton transfer from sulfamic acid to the pyridine N atom occurred, resulting in the formation of a salt. As expected, this protonation leads to the widening of the C-N-C angle of the pyridine ring, to 122.9?(3)°, with the pyridinium ring being essentially planar (r.m.s. deviation = 0.025?Å). In the crystal, the ion pairs are joined by three N-H?O and one N-H?N hydrogen bonds in which the pyridinium N atom and the amino N atom act as donors, and are hydrogen bonded to the carboxyl-ate O atoms and the N atom of the sulfamate anion, thus generating an R (3) 3(22) ring motif. These motifs are linked by further N-H?O hydrogen bonds enclosing R (3) 3(8) loops, forming sheets parallel to (100). The sheets are linked via weak C-H?O hydrogen bonds, forming a three-dimensional structure. The O atoms of the nitro group are disordered over two sets of sites with a refined occupancy ratio of 0.737?(19):0.263?(19).

Crystal structure of 4-(di-methyl-amino)-pyridinium 4-amino-benzoate dihydrate.

Project description:In the title hydrated mol-ecular salt, C7H11N2 (+)·C7H6NO2 (-)·2H2O, the cation is protonated at the pyridine N atom and the dihedral angle between the benzene ring and the CO2 (-) group in the anion is 8.5 (2)°. In the crystal, the cation forms an N-H⋯O hydrogen bond to the anion and the anion forms two N-H⋯O hydrogen bonds to adjacent water mol-ecules. Both water mol-ecules form two O-H⋯O hydrogen bonds to carboxyl-ate O atoms. In combination, these hydrogen bonds generate a three-dimensional network and two weak C-H⋯π inter-actions are also observed.

2-Amino-5-chloro-pyridinium nitrate.

Project description:The title structure, C(5)H(6)ClN(2) (+)·NO(3) (-), is held together by extensive hydrogen bonding between the NO(3) (-) ions and 2-amino-5-chloro-pyridinium H atoms. The cation-anion N-H?O hydrogen bonds link the ions into a zigzag- chain which develops parallel to the b axis. The structure may be compared with that of the related 2-amino-5-cyano-pyridinium nitrate.

2-Amino-5-chloro-pyridinium salicylate.

Project description:In the crystal structure of the title salt, C(5)H(6)ClN(2) (+)·C(7)H(5)O(3) (-), the protonated N atom and the 2-amino group of the cation are hydrogen bonded to the carboxyl-ate O atoms via a pair of N-H⋯O hydrogen bonds, forming R(2) (2)(8) ring motifs. These motifs are centrosymmetrically paired via N-H⋯O hydrogen bonds, forming a complementary donor-donor-acceptor-acceptor (DDAA) array. A typical intra-molecular O-H⋯O hydrogen bond is also observed in the salicylate anion. The crystal structure is further stabilized by weak C-H⋯π inter-actions.

In the crystal, the cations and anions are linked via N-H⋯O and C-H⋯O hydrogen bonds, forming a two-dimensional network parallel to (001).
