摘要

The synthesis of 4-aza­niumyl-2,2,6,6-tetra­methyl­piperidin-1-ium diperchlorate, C9H22N22+·2ClO4−, was carried out from an aqueous reaction of perchloric acid with 4-amino-2,2,6,6-tetra­methyl­piperidine. This compound was characterized by TGA–DSC analysis and single-crystal X-ray diffraction. The piperidine ring of the dication adopts a chair conformation and the orientation of the C—NH3 bond is equatorial. One of the two crystallographically independent perchlorate anions exhibits disorder [occupancies 0.625 (7) and 0.375 (7)]. The crystal packing is constituted by a succession of mixed layers parallel to the (-102) plane, made up of C9H22N22+ dications and ClO4− anions. These ions are linked by normal and bifurcated N—H⋯O hydrogen bonds with R44(12) graph-set motifs, generating a two-dimensional network. The inter­molecular inter­actions in the crystal structure were qu­anti­fied and analysed using Hirshfeld surface analysis.
