In the title salt, C18H24NO+·C6H7O7, the dihedral angle between the benzene rings in the cation is 74.2 (5)°. In the crystal, anion–anion O—H...O hydrogen bonds and weak O—H...O inter­actions form infinite chains along [100]. Between these chains, cation–anion N—H—O hydrogen bonds are observed, forming an alternate pattern of cation and anion layers and leading to a two-dimensional network parallel to (100).

Three independent mol­ecules comprise the asymmetric unit of the title compound, C10H19N5O2, (systematic name: 4-amino-N-tert-butyl-3-isopropyl-5-oxo-4,5-dihydro-1H-1,2,4-triazole-1-carboxamide) . In all three mol­ecules, the triazole ring and the carboxamide group are almost coplanar [within 4.0–5.9 (9)°], particularly because of the formation of an intra­molecular N—H...O hydrogen bond. On other hand, the orientation of the isopropyl group varies significantly from mol­ecule to mol­ecule. The crystal packing is dominated by N—H...O and N—H...N hydrogen bonds, which connect the mol­ecules into infinite chains along [010].

In the title salt, C14H20NO+·Cl, the piperidine ring adopts a chair conformation. In the crystal, the cations and anions are linked by classical N—H...Cl hydrogen bond and weak C—H...Cl and C—H...O hydrogen bonds; the C—H...O hydrogen bonds exhibit R22(14) ring motifs while the C—H...Cl hydrogen bonds link the mol­ecules into chains along the a-axis direction. π–π stacking is observed between parallel phenyl rings of adjacent cations, the centroid–centroid distance being 3.8164 (15) Å.
