Definition
ChEBI: A monohydroxypyridine that is the 6-hydroxy derivative of nicotinic acid.
General Description
6-Hydroxypyridine-3-carboxylic acid (6-Hydroxynicotinic acid) reacts with Ln(2)O(3) (Ln = Nd, Sm, Eu, Gd) and oxalic acid (H(2)OX) to generate four novel lanthanide-organic coordination polymeric networks.
Purification Methods
It crystallises from water with m 303.4-303.7o(dec), or with m 325o(dec) from aqueous EtOH. The methyl ester crystallises from Me2CO with m 166o and pK2 0 9.92. [Albert J Chem Soc 1020 1960, Beilstein 22 III/IV 2147, 22/6 V 119.]
