In the crystal structure of the title salt, C9H22N22+·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—HO hydrogen bonds in R22(6), two R42(8) and R34(14) graf-set motifs, generating a three-dimensional network.
