4-(Dimethyl-amino)pyridinium tribromide: whole mol-ecule disorder of cation and anion.

ABSTRACT: In the title salt, C(7)H(11)N(2) (+)·Br(3) (-), the cation and the near-linear anion [Br-Br-Br = 179.41?(8)°] both show whole-mol-ecule disorder about crystallographic twofold rotation axes. The cation is weakly hydrogen-bonded to the anion by an N-H?Br inter-action. The crystal studied was found to be a racemic twin, with a twin component of nearly 50%.

4-(Dimethyl-amino)pyridinium tribromide: whole mol-ecule disorder of cation and anion.

Acta crystallographica. Section E, Structure reports online 20090514 Pt 6

In the title salt, C(7)H(11)N(2) (+)·Br(3) (-), the cation and the near-linear anion [Br-Br-Br = 179.41 (8)°] both show whole-mol-ecule disorder about crystallographic twofold rotation axes. The cation is weakly hydrogen-bonded to the anion by an N-H⋯Br inter-action. The crystal studied was found to be a racemic twin, with a twin component of nearly 50%. ...[more]

Redetermination of 4-(dimethyl-amino)-pyridinium tribromide.

Project description:In the title salt, C(7)H(11)N(2) (+)·Br(3) (-), the essentially planar cation (r.m.s. deviation = 0.006 Å) forms an N-H⋯Br hydrogen bond to one of the Br atoms of the almost linear anion [Br-Br-Br = 179.31 (2)°]. The crystal studied was found to be a racemic twin. The whole-mol-ecule disorder of the cation and anion about a twofold rotation axis described earlier [Ng (2009). Acta Cryst. E65, o1276] is an artifact of halving one of the axes of the ortho-rhom-bic unit cell.

Ortho-rhom-bic modification of (E)-4-benzyl-idene-2-phenyl-1,3-oxazol-5(4H)-one: whole mol-ecule disorder.

Project description:The title mol-ecule, C(16)H(11)NO(2), is disordered about a pseudo-twofold rotation axis that approximately bis-ects the mol-ecule along the C=O double bond. The two overlapping components are planar [r.m.s. deviation = 0.10?Å in the major 0.537?(4) component and 0.07?Å in the minor component]. The two components are aligned at 1.8?(3)°.

6-Isopropyl-3-phenyl-5-(p-tol-yloxy)-3H-1,2,3-triazolo[4,5-d]pyrimidin-7(6H)-one: whole-mol-ecule disorder.

Project description:The title compound, C(20)H(19)N(5)O(2), exhibits whole-mol-ecule disorder the refined ratios of the two components being 0.57?(2):0.43?(2). In the major component, the essentially planar [maximum deviation 0.033?(17)?Å] fused pyrimidine and triazole ring system forms a dihedral angle of 10.5?(3)° with the phenyl ring, while in the minor component of disorder this angle is 27.5?(5)°. The crystal structure is stabilized by ?-? stacking inter-actions between symmetry-related triazole and pyrimidine rings, with centroid-centroid distances of 3.594?(10)?Å.

2-Amino-4,6-dimethyl-pyridinium benzoate.

Project description:In the title compound, C(7)H(11)N(2) (+)·C(7)H(5)O(2) (-), the 2-amino-4,6-dimethyl-pyridinium cation and the benzoate anion are linked by two N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. The H atoms in both the methyl groups are rotationally disordered, with fixed site occupancies of 0.50. In the crystal structure, the mol-ecules are stabilized by inter-molecular N-H⋯O hydrogen bonds. A π-π inter-action, with a centroid-centroid distance of 3.661 (2) Å, is also observed.

Whole-mol-ecule disorder of the Schiff base compound 4-chloro-N-(4-nitro-benzyl-idene)aniline: crystal structure and Hirshfeld surface analysis.

Project description:In the crystal of the title Schiff base compound, C13H9ClN2O2, [CNBA; systematic name: (E)-N-(4-chloro-phen-yl)-1-(4-nitro-phen-yl)methanimine], the CNBA mol-ecule shows whole-mol-ecule disorder (occupancy ratio 0.65:0.35), with the disorder components related by a twofold rotation about the shorter axis of the mol-ecule. The aromatic rings are inclined to each other by 39.3 (5)° in the major component and by 35.7 (9)° in the minor component. In the crystal, C-H⋯O hydrogen bonds predominate in linking the major components, while weak C-H⋯Cl inter-actions predominate in linking the minor components. The result is the formation of corrugated layers lying parallel to the ac plane. The crystal packing was analysed using Hirshfeld surface analysis and compared with related structures.

2-Amino-4,6-dimethyl-pyridinium chloride dihydrate.

Project description:In the title hydrated mol-ecular salt, C(7)H(11)N(2) (+)·Cl(-)·2H(2)O, the pyridine N atom of the 2-amino-4,6-dimethyl-pyridine mol-ecule is protonated. The cation is essentially planar, with a maximum deviation of 0.006?(2)?Å. In the crystal, the components are linked by N-H?O, N-H?Cl and O-H?Cl hydrogen bonds, thereby forming sheets lying parallel to (100). The crystal structure is further stabilized by aromatic ?-? stacking inter-actions between the pyridinium rings [centroid-centroid distance = 3.4789?(9)?Å].

4-(Dimethyl-amino)pyridinium 4-toluene-sulfonate.

Project description:In the title compound, C(7)H(11)N(2) (+)·C(7)H(7)O(3)S(-), the cation is protonated at the N atom of the heterocyclic ring. The dimethyl-amino group lies close to the pyridinium ring plane with a dihedral angle between the pyridinium and the dimethyl-amine CNC planes of 3.82?(17)°. The N-C bond linking the dimethyl-amino substituent to the pyridinium ring is characteristically short [1.3360?(19)?Å], suggesting some delocalization in the cation. In the crystal structure, N-H?O hydrogen bonds link individual pairs of cations and anions. The structure is further stabilized by an extensive series of C-H?O hydrogen bonds, augmented by ?-? [centroid-centroid distance between adjacent pyridinium rings = 3.5807?(10)?Å] and C-H?? inter-actions, giving a network structure.

Bis[4-(dimethyl-amino)-pyridinium] tetra-chloridozincate.

Project description:In the title compound, (C(7)H(11)N(2))(2)[ZnCl(4)], [ZnCl(4)](2-) anions and 4-(dimethyl-amino)-pyridinium cations are held together by various inter-molecular inter-actions including Coulombic attraction, hydrogen bonding and π-π stacking inter-actions. Three Cl atoms of the [ZnCl(4)](2-) tetra-hedron act as acceptors in N-H⋯Cl hydrogen bonds. The hydrogen bonds, both of which are bifurcated, lead to the formation of a three-dimensional network. Within the network, inter-molecular π-π stacking inter-actions with a centroid-centroid distance of 3.5911 (7) Å arrange the 4-(dimethyl-amino)-pyridinium cations into anti-parallel dimers.
