Abstract
The rare earth salicylate monohydrates Ln(C6H4OHCOO)3·H2O (Ln=La-Ho or Y) were prepared and subjected to X-ray powder diffractometric and infrared absorption spectroscopic investigations. The salts from lanthanum to gadolinium are found to be isomorphous and are indexed on a monoclinic unit cell with space groupP21/c-C 52h (No. 14). Certain dissimilarities between the powder patterns of isomorphous terbium and dysprosium compounds and those of the lighter rare earths necessitated independent indexing of these two compounds, which are found to be monoclinic with space groupP21/c-C 52h . Holmium and yttrium salts are isomorphous and are monoclinic with space groupP2/m-C 12h (No. 10). The assignments of some of the observed bands to certain characteristic vibrations of various functional groups in the spectra of these salts have been done.
