4-(Dimethyl-amino)pyridinium 2-(4-hydroxy-phenyl-diazen-yl)benzoate.

ABSTRACT: In the title molecular salt, C(7)H(11)N(2) (+)·C(13)H(9)N(2)O(3) (-), the dihedral angle between the benzene rings in the anion is 35.14 (8)°. In the crystal, centrosymmetrically related anions associate via hydrox-yl-carboxyl-ate O-H⋯O hydrogen bonds, resulting in a 24-membered {⋯OC(3)N(2)C(4)OH}(2) synthon. The cations are associated with this dimeric unit via pyridinium-carboxyl-ate N-H⋯O hydrogen bonds. Weak C-H⋯O links further consolidate the packing, generating layers.

1H-Benzotriazol-1-yl 4-{(E)-[4-(dimethyl-amino)-phen-yl]diazen-yl}benzoate.

Project description:The title compound, C(21)H(18)N(6)O(2), was obtained as a by-product of a reaction between (E)-4-(4-dimethyl-amino-phenyl-azo)benzoic acid and 2-amino-4-(2-pyrid-yl)-6-(6-pyrid-yl)-1,3,5-triazine, which has a very low solubility, under peptidic coupling conditions, using THF as solvent. The condensation reaction occurred between 1-hy-droxy-benzotriazole and (E)-4-(4-dimethyl-amino-phenyl-azo)benzoic acid. The dihedral angle between the benzene rings in the (E)-diphenyl-diazene fragment is 10.92?(13)° and that between the benzotriazole mean plane and the central benzene ring is 80.57?(7)°. In the crystal, ?-? stacking [centroid-centroid distances = 3.823?(2) and 3.863?(2)?Å] of similar fragments generates mol-ecular layers parallel to (0-12). The crystal packing also features weak C-H?N hydrogen bonds involving N atoms of the benzotriazole ring.

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 ?-? inter-action, with a centroid-centroid distance of 3.661?(2)?Å, is also observed.

2-{2-[4-(Dimethyl-amino)-phen-yl]diazen-1-ium-1-yl}pyridinium tetra-chlorido-zincate.

Project description:The title compound, (C(13)H(16)N(4))[ZnCl(4)], consists of a tetra-hedral [ZnCl(4)](2-) anion and a 2-{2-[4-(dimethyl-amino)-phen-yl]diazen-1-ium-1-yl}pyridinium dication. The pyridinium-N atom is syn to the azo bond which allows for the formation of an intramolecular N-H?N hydrogen bond. In the crystal, the cation and anion are held together by N-H?Cl hydrogen-bond inter-actions involving the pyridinium and diazen-1-ium N atoms. ?-? stacking inter-actions occur between the pyridine and benzene rings of adjacent cations [centroid-centroid distances = 3.6270?(18) and 3.8685?(18)?Å]; the stacks are parallel to the a axis.

2-(Dimethyl-amino-meth-yl)phenyl phenyl telluride.

Project description:The title compound, C(15)H(17)NTe, is a heteroleptic Te, N-bidentate ligand having a short Te?N contact [2.8079?(16)?Å] involving a secondary bonding inter-action between the amino N and Te(II) atoms. The Te-C bond [2.136?(2)?Å] trans to the amino group is slightly elongated compared to the other Te-C bond [2.1242?(18)?Å] due to the hypervalent inter-action. The bond angle for the trans N-Te-C atoms [164.92?(6)°] deviates significantly from linearity.
