N2 - Samarium(III) tris-dipivaloylmethanate [Sm(dpm)3]2 (I) and sodium samarium(III) tetrakishexafluoroacetylacetonate [NaSm(hfa)4]n (II) are obtained. The crystal structures of I at 150(2) K (space group P21/n, a = 12.279(1) Å, b = 27.726(3) Å, с = 21.884(2) Å, β = 105.317(3)°, V = 7186.0(11) Å3, Z = 4) and II at 150(2) K (space group C2/c, a = 21.693(2) Å, b = 12.2068(7) Å, с = 14.402(1) Å, β = 124.731(3)°, V = 3134.2(4) Å3, Z = 4) are determined. The structure of the complex I is similar to that of the previously known dimeric [Ln(dpm)3]2 (Ln = La, Pr, Nd, Eu, Gd, Tb) complexes; and the structure of the complex II is similar to that of the known [NaLn(hfa)4]n (Ln = Y, Eu, Er) complexes. It is shown by thermogravimetry that the volatility of REE tris-dipivaloylmethanates increases from Lu to La, the volatility of REE sodium tetrakis-hexafluoroacetylacetonates increases from La to Lu.
