o-Phenyl­enediaminium chloride nitrate

In the title mol­ecular salt, C₆H₁₀N₂²⁺·NO₃⁻·Cl⁻, the complete cation is generated by a crystallographic mirror plane. The complete nitrate ion is also generated by reflection, with the N atom and one O atom lying on the mirror plane; the chloride ion also lies on the reflection plane. In the crystal, the components are linked by N—H...Cl and N—H...(N,O) hydrogen bonds, forming (001) layers with the benzene rings projecting into the inter­layer regions. The layers are linked by weak C—H...O hydrogen bonds, generating a three-dimensional network.

3-(Ammonio­methyl)­pyridinium bis­(perchlorate)

In the title molecular salt, C₆H₁₀N₂²⁺·2ClO₄⁻, the Cl—O bond lengths [anion 1: 1.369 (3)–1.415 (3); anion 2: 1.420 (2)–1.441 (2) Å] and the O—Cl—O angles [anion 1: 105.4 (2)–111.8 (4); anion 2: 107.8 (1)–110.3 (1)°] indicate a slight distortion of the perchlorate anions from regular tetra­hedral symmetry. In the crystal, the components are linked into columns along the a-axis direction via N—H...O and C—H...O hydrogen bonds, with stacks of the organic mol­ecules being surrounded by stacks of perchlorate anions.
