Abstract

The preparation of lanthanum hydroxide bromide and its hydrates, La(OH)2Br · nH2O (n = 0.0, 1.0, 1.5) is described. Crystal data for these compounds are La(OH)2Br · 1.5H2O: hexagonal, a = 8.435 ± 0.001, b = 4.230 ± 0.001 Å, space group P6mm or P6 mmm; La(OH)2Br: monoclinic, a = 6.374 ± 0.001, b = 4.031 ± 0.001, c = 7.160 ± 0.001 Å, β = 113.12 ± 0.01°, space group P21 or P21 m. The infrared spectra of these compounds are presented, and they are discussed in relation to their structures. The thermal decomposition behaviors are determined with a thermobalance.
