摘要
The title compound, poly[[ mu-3-hydroxy-2-(2-hydroxybenzylideneamino) propionato] potassium], [K( C10H10NO4)](n), is an effective material for preparing rare earth Eu complexes. It is composed of planar six-membered rings and planar five-membered rings formed by intramolecular O - H center dot center dot center dot N hydrogen bonding, which are oriented with respect to each other at a dihedral angle of 3.56 ( 4)degrees. The K+ ion is surrounded by seven O atoms, five from three carboxylate groups and two from two hydroxyl groups. In the crystal structure, intermolecular O - H center dot center dot center dot O hydrogen bonds result in the formation of chains along the c axis.
