4-Methylpyridinium 2-carboxy-6-nitrobenzoate
Abstract
In the title molecular salt, C6H8N+·C8H4NO6−, the anion is deprotonated at the carboxylic acid group adjacent to the nitro group. In the crystal, the anions are linked into an [001] chain by O—H...O hydrogen bonds. The cations are linked to these chains by N—H...O hydrogen bonds and weak C—H...O contacts, generating a three-dimensional network.
