2-({[(Pyridin-1-ium-2-ylmeth-yl)carbamo-yl]form-amido}-meth-yl)pyridin-1-ium bis-(3,5-di-carb-oxy-benzoate): crystal structure and Hirshfeld surface analysis.

Project description:The asymmetric unit of the title salt, C14H16N4O2 (2+)·2C9H5O6 (-), comprises half a dication, being located about a centre of inversion, and one anion, in a general position. The central C4N2O2 group of atoms in the dication are almost planar (r.m.s. deviation = 0.009 Å), and the carbonyl groups lie in an anti disposition to enable the formation of intra-molecular amide-N-H⋯O(carbon-yl) hydrogen bonds. To a first approximation, the pyridinium and amide N atoms lie to the same side of the mol-ecule [Npy-C-C-Namide torsion angle = 34.8 (2)°], and the anti pyridinium rings are approximately perpendicular to the central part of the mol-ecule [dihedral angle = 68.21 (8)°]. In the anion, one carboxyl-ate group is almost coplanar with the ring to which it is connected [Cben-Cben-Cq-O torsion angle = 2.0 (3)°], whereas the other carboxyl-ate and carb-oxy-lic acid groups are twisted out of the plane [torsion angles = 16.4 (3) and 15.3 (3)°, respectively]. In the crystal, anions assemble into layers parallel to (10-4) via hy-droxy-O-H⋯O(carbon-yl) and charge-assisted hy-droxy-O-H⋯O(carboxyl-ate) hydrogen bonds. The dications are linked into supra-molecular tapes by amide-N-H⋯O(amide) hydrogen bonds, and thread through the voids in the anionic layers, being connected by charge-assisted pyridinium-N-O(carboxyl-ate) hydrogen bonds, so that a three-dimensional architecture ensues. An analysis of the Hirshfeld surface points to the importance of O-H⋯O hydrogen bonding in the crystal structure.

4-Carb-oxy-pyridin-1-ium 2,4,5-tri-carb-oxy-benzoate monohydrate.

Project description:The title hydrated salt, C6H6NO2 (+)·C10H5O8 (-)·H2O, was isolated from the 1:1 cocrystallization of benzene-1,2,4,5-tetra-carb-oxy-lic acid and isonicotinic acid in ethanol solution. In the crystal, the cation is close to planar [r.m.s. deviation = 0.085 Å for the nine fitted atoms; the C-C-C-O(carbon-yl) torsion angle = -8.7 (4)°], but twists are evident in the anion, with all but the carb-oxy-lic acid group diagonally opposite the carboxyl-ate group being significantly twisted out of the plane of the benzene ring [C-C-C-O(carbon-yl) torsion angles = -118.1 (2), -157.6 (2), 4.3 (3) and 77.3 (3)°]. In the crystal, the ions and water mol-ecules are consolidated into a three-dimensional architecture by O-H⋯O and N-H⋯O hydrogen bonding along with C-H⋯O inter-actions.

1-Methyl-3-(4-chloro-benzo-yl)imidazo[1,2-a]pyridin-1-ium-2-olate.

Project description:In the mol-ecule of the title compound, C(15)H(11)ClN(2)O(2), the nine-membered heterobicycle is approximately planar [largest deviation from least-squares plane = 0.012?(2)?Å] and forms a dihedral angle of 51.14?(8)° with the plane of the 4-chloro-phenyl group. There is a non-classical intra-molecular hydrogen bond between the pyridine ?-H atom and the O atom of the benzoyl group. The crystal structure is stabilized by weak C-H?O and C-H?Cl inter-actions involving the 'olate' O atom and the Cl atom attached to the benzoyl group as acceptors.

Crystal structure and Hirshfeld surface analysis of two imidazo[1,2-a]pyridine derivatives: N-tert-butyl-2-(4-meth-oxy-phen-yl)-5-methyl-imidazo[1,2-a]pyridin-3-amine and N-tert-butyl-2-[4-(di-methyl-amino)-phen-yl]imidazo[1,2-a]pyridin-3-amine.

Project description:In the title imidazo[1,2-a]pyridine derivatives, N-tert-butyl-2-(4-meth-oxy-phen-yl)-5-methyl-imidazo[1,2-a]pyridin-3-amine, C19H23N3O, (I), and N-tert-butyl-2-[4-(di-methyl-amino)-phen-yl]imidazo[1,2-a]pyridin-3-amine, C19H24N4, (II), the 4-meth-oxy-phenyl ring in (I) and the 4-(di-methyl-amino)-phenyl ring in (II) are inclined to the respective imidazole rings by 26.69?(9) and 31.35?(10)°. In the crystal of (I), mol-ecules are linked by N-H?N hydrogen bonds, forming chains propagating along the [001] direction. The chains are linked by C-H?? inter-actions, forming layers parallel to the (010) plane. In (II), the crystal packing also features N-H?N hydrogen bonds, which together with C-H?N hydrogen bonds link mol-ecules to form chains propagating along the c-axis direction. The chains are linked by C-H?? inter-actions to form layers parallel to the (100) plane. Inversion-related layers are linked by offset ?-? inter-actions [inter-centroid distance = 3.577?(1)?Å]. The inter-molecular inter-actions of both compounds were analyzed using Hirshfeld surface analysis and two-dimensional fingerprint plots.

3-Ethyl-5-(4-meth-oxy-phen-oxy)-2-(pyridin-4-yl)-3H-imidazo[4,5-b]pyridine.

Project description:In the title compound, C(20)H(18)N(4)O(2), the imidazopyridine fused ring system is almost perpendicular to the benzene ring [dihedral angle = 87.6?(5)°]. The pyridine ring makes a dihedral angle of 35.5?(5)° with the mean plane of the imidazopyridine fragment. The crystal structure is stabilized by an aromatic ?-? stacking inter-action between the phenyl rings of neighbouring mol-ecules [centroid-centroid distance = 3.772?(2)?Å, inter-planar distance = 3.546?(2)?Å and slippage = 1.286?(2)?Å].

3-(2,6-Dimethyl-anilino)imidazo[1,2-a]pyridin-1-ium perchlorate.

Project description:The structure of the organic cation in the title compound, C(15)H(16)N(3) (+)·ClO(4) (-), contains two essentially planar rings. Mean planes fitted through all non-H atoms of each ring system have an r.m.s. deviation of 0.019?Å for the imidazole-based ring and 0.016?Å for the 2,6-dimethyl-phenyl ring. The angle between the two planes is 86.76?(2)°. In the crystal structure, N-H?O inter-actions form a one-dimensional chain, which propagates in the b-axis direction. C-H?O inter-actions are also found in the crystal packing.

(E)-2-[2-(4-Carb-oxy-phen-yl)ethen-yl]-8-hydroxy-quinolin-1-ium chloride ethanol monosolvate.

Project description:In the title compound, C18H14NO3 (+)·Cl(-)·CH3CH2OH, the dihedral angle formed by the mean planes of the quinolinium and benzene rings is 3.4 (1)°, while the carb-oxy substituent is tilted at an angle of 4.8 (1)° with respect to the benzene ring. There is a short N-H⋯O contact in the cation. In the crystal, due to the planar mol-ecular geometry, two-dimensional aggregates are formed parallel to (221) via C-H⋯O, C-H⋯Cl, O-H⋯Cl and N-H⋯Cl hydrogen bonds. Inter-layer association is accomplished by O-Hethanol⋯Cl and O-H⋯Oethanol hydrogen bonds and π-π stacking inter-actions [centroid-centroid distances vary from 3.6477 (12) to 3.8381 (11) Å]. A supra-molecular three-dimensional architecture results from a stacked arrangement of layers comprising the ionic and hydrogen-bonded components.
