Structure cristalline et analyses thermique et de surface Hirshfeld du diperchlorate de 4-aza-niumyl-2,2,6,6-tetramethylpiperidin-1-ium.


ABSTRACT: The synthesis of 4-aza-niumyl-2,2,6,6-tetra-methyl-piperidin-1-ium diperchlorate, C9H22N22+·2ClO4-, was carried out from an aqueous reaction of perchloric acid with 4-amino-2,2,6,6-tetra-methyl-piperidine. 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 inter-molecular inter-actions in the crystal structure were qu-anti-fied and analysed using Hirshfeld surface analysis.
