Abstract
The crystal structure of the monohydrated proton-transfer compound of 3,5-dinitrosalicylic acid with piperidine shows the presence of dianionic 3,5-dinitrosalicylate species, as well as partial monoanionic 3,5-dinitrosalicylate and picrate species; the formula is 3C5H12N+·C7H3N2O7−·0.79C7H2N2O72−·0.21C6H2N3O7−·H2O. All available proton-donor species, including the solvent water molecule, are involved in hydrogen-bonding interactions with O-atom acceptors on the anion species, giving a one-dimensional column polymer structure, with further structure extension through anion–anion π–π ring interactions.
