The crystal structure of Poly[[diaquabis(μ-oxalato-κ4O1,O2:O1′,O2′)bis(μ3-5-oxidopyridin-1-ium-3-carboxylato-κ3O3:O3′:O5)diholmium(III)] dihydrate] has been determined The HoIII atom was coordinated by three O atoms from three 5-hydroxynicotinate ligands, four O atoms from two oxalate ligands, each lying on an inversion center, and one water mol. in a distorted square-antiprismatic geometry. The 5-hydroxynicotinate ligand was protonated at the N atom and deprotonated at the hydroxy group. The HoIII atoms were bridged by the carboxylate and phenolate O atoms, forming a three-dimensional framework. N-H···O and O-H···O hydrogen bonds, as well as π-π interactions between the pyridine rings [centroid-centroid distance = 3.794(2) Å], were observed
This compound(5-Hydroxynicotinic acid)HPLC of Formula: 27828-71-3 was discussed at the molecular level, the effects of temperature and reaction time on the properties of the compound were discussed, and the optimum reaction conditions were selected.
