Abstract
A series of yttrium subgroup rare earth elements (REE) lactates of [Ln(C3H5O3)3(H2O)2] (Ln = Tb–Lu) composition isostructural to yttrium lactate has been prepared for the first time. Synthesis of crystalline REE lactates has been performed from solutions of REE nitrates in the presence of L-lactic acid and hexamethylenetetramine. The composition and structure of the obtained compounds have been confirmed by X-ray powder diffraction, thermal, and chemical (CHN) analysis. The coordination type of lactate anions to REE cations has been determined by IR spectroscopy. Thermal decomposition of REE lactates at 800°C leads to formation of nanocrystalline (20–40 nm) REE (Y, Tb–Lu) oxides.
