Preparation and Structural Characterization of Lanthanum Hydroxide Hydrogen Diphthalate Monohydrate

Abstract

Abstract: The LaOH(C₈H₅O₄)₂·H₂O was prepared by employing water film reaction method. The electron and X-ray diffraction patterns show that the complex belongs to a monoclinic system, Plal, Z=4, α=2. 0587 nm, b=0. 6235 nm, c=1. 3113 nm, β=94. 64°. The IRspectrum was recorded with a FT-IRspectrometer, and the vibrational bands were assigned by comparison with that of calcium phthalate monohydrate. The coordinate structure of carboxylate groups with lanthanum ions was discussed.

Key words: 1,2-Benzenedicarboxylic acid, Lanthanum complex, Crystal structure, Infrared spectrum, Water film reaction
