Structure cristalline et analyses thermique et de surface Hirshfeld du diperchlorate de 4-azaniumyl-2,2,6,6-tétraméthylpipéridin-1-ium
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—NH3bond 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 withR44(12) graph-set motifs, generating a two-dimensional network. The intermolecular interactions in the crystal structure were quantified and analysed using Hirshfeld surface analysis.
