Mixed 3,5-dinitrosalicylate(2-) and partial 3,5-dinitrosalicylate(1-) and picrate(1-) species in tris(piperidinium) bis(3,5-dinitrosalicylate) picrate monohydrate
MetadataShow full item record
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+烷H3N2O7-簮79C7H2N2O72-簮21C6H2N3O7-爲O. 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 [pi]-[pi] ring interactions.
