In the crystal structure of the title compound intermolecular hydrogen-bonding interactions and weak C—H
π interactions between the constituents lead to the formation of a three-dimensional network. Hirshfeld surface analysis revealed that HH interactions dominate the crystal packing.

The title compound, C22H32O6, is a sesquiterpene isolated from Pluchea carolinensis (Compositae). The X-ray structure is consistent with a compound isolated from other species of Pluchea and elucidated from spectroscopic data [Nakanishi, Crouch, Miura, Dominguez, Zamudio & Villarreal (1974). J. Am. Chem. Soc. 96, 609-611].

The title compound exists in the crystal as a dimer of ion pairs. Hydrogen bonding and weak π–π interactions along with N—Hπ interactions are involved in consolidating this cluster. The three-dimensional crystal structure consists of stepped stacks of dimers of ion pairs associated by C—Hπ(ring) and slipped π-stacking interactions.

In the title molecule, C16H9NO5S, there is an intramolecular O—HO hydrogen bond involving the quinolone carbonyl O atom and a carboxyl OH group. In the crystal, intermolecular O—HO hydrogen bonds between the carbonyl group of the quinolone carboxyl group, and a second carboxyl group on the thiazeto moiety lead to the formation of chains propagating along [201] and perpendicular to the π-stacks of molecules.

In the crystal, hydrogen-bonding interactions between the 2,4,6-triaminopyrimidine cation and the nitrate anions lead to a one-dimensional supramolecular network with weak anionic interactions forming a three-dimensional network. Energy framework analysis showed that of the components of the framework energies, electrostatic repulsion (Erep) is dominant.
