Abstract
Coordination compounds of yttrium(III) nitrate with urea (Ur) and N,N-dimethylacetamide, [Y(H2O)(Ur)2(NO3)3] (I), [Y(Ur)3(NO3)3] (II) and [Y(DMAA)3(NO3)3] (III), were synthesized; their compositions, structural features and thermolysis were studied with the use of elemental analysis, IR spectroscopy, X-ray powder and single-crystal diffraction, thermal gravimetric analysis, differential scanning calorimetry. The coordination compounds can be used for the synthesis of nano-scale yttrium(III) oxide.
