چکیده
In the crystal structure of the title salt, C9H22N2 (2+)·2NO3 (-), the piperidine ring of the dication adopts a chair conformation and the orientation of the C-NH3 bond is equatorial. The ions are linked by normal and bifurcated N-H⋯O hydrogen bonds in R 2 (2)(6), two R 4 (2)(8) and R 3 (4)(14) graf-set motifs, generating a three-dimensional network.
