3,5-Dicarboxypyridinium fluoride
The cation of the title salt, C(7)H(6)NO(4) (+.)F(−), lies on a twofold rotation axis that passes through the N and 4-C atoms of the pyridine ring; the carboxylic acid substituent features unambiguous carbon–oxygen single and double bonds. The fluoride ion is a hydrogen-bond acceptor to two hydro...

description | The cation of the title salt, C(7)H(6)NO(4) (+.)F(−), lies on a twofold rotation axis that passes through the N and 4-C atoms of the pyridine ring; the carboxylic acid substituent features unambiguous carbon–oxygen single and double bonds. The fluoride ion is a hydrogen-bond acceptor to two hydroxy and one amino groups, these O—H⋯F and N—H⋯F hydrogen bonds leading to the formation of a layer structure parallel to the ab plane. The F atom lies on a position of 2 site symmetry. |
