4-Carboxy-pyridazin-1-ium chloride.

ABSTRACT: The structure of the title compound, C(5)H(5)N(2)O(2) (+)·Cl(-), is composed of chloride anions and 4-carboxy-pyridazin-1-ium cations. Chloride anions bridge the cations via O-H?Cl and N-H?Cl hydrogen bonds to form ribbons. The latter, linked by van der Waals forces with lengths in the range 3.254?(2)-3.497?(2)?Å, form coplanar layers. Very weak inter-actions operate also between adjacent layers, as indicated by their spacing of 3.339?(1)?Å.

The structure of the title compound, C(5)H(5)N(2)O(2) (+)·Cl(-), is composed of chloride anions and 4-carboxy-pyridazin-1-ium cations. Chloride anions bridge the cations via O-H⋯Cl and N-H⋯Cl hydrogen bonds to form ribbons. The latter, linked by van der Waals forces with lengths in the range 3.254 (2)-3.497 (2) Å, form coplanar layers. Very weak inter-actions operate also between adjacent layers, as indicated by their spacing of 3.339 (1) Å. ...[more]

4-(4-Carboxy-benz-yl)-1-methyl-piperazin-1-ium picrate.

Project description:The title compound, C(13)H(19)N(2)O(2) (+)·C(6)H(2)N(3)O(7) (-), is a salt obtained by cocrystallization of 4-[(4-methyl-piperazin-1-yl)meth-yl]benzoic acid and picric acid.

The NH group of each piperazinium ring forms a hydrogen bond to the phenolate O atom of a picrate anion, and the picrate anions form face-to-face contacts with an inter-planar separation of 3.023?(1)?Å.
