Abstract

Coordination compounds of rare earth nitrates with acetamide (AA), [Ln(AA)4(NO3)3] (Ln = La (I), Ce (II), Pr (III), Nd (IV)), [Sm(AA)3(H2O)(NO3)3] (V), and [Ln(AA)3(NO3)3] (Ln = Tb (VI), Dy (VII), Er (VIII), Yb (IX)), were synthesized and characterized by physicochemical methods (ICP MS, elemental analysis, IR spectroscopy, powder X-ray diffraction, thermal gravimetric analysis, and differential scanning calorimetry). Molecular structures of complexes I, II, IV, V, and VIII were determined by single-crystal X‑ray diffraction (CCDC nos. 2 370 600 (I); 2 203 371 (II); 2 203 372 (IV); 2 370 601 (V); 2 370 602 (VIII)). Thermolysis of the compounds was studied in a wide temperature range. The synthesized coordination compounds can be used for the preparation of nanosized oxides.
