Abstract
A series of Ln(III) dipivaloylmethanates of the composition Ln(dpm)3 (Ln = La, Tm, Yb) is obtained. It is established that Tm(dpm)3 and Yb(dpm)3 complexes are isostructural with Lu(dpm)3. The crystal structure of [La(dpm)3]2 at 150(2) K is determined (space group P21/n, a = 12.4412(5) Å, b = 28.0579(12) Å, с = 21.9533(8) Å, β = 105.796(2)°, V = 7373.9(5) Å3, Z = 4). The studied compound is isostructural with [Pr(dpm)3]2, [Eu(dpm)3]2, [Gd(dpm)3]2, and [Tb(dpm)3]2 complexes. The crystal structure of the complex is formed by dimeric [La(dpm)3]2 molecules. Thermogravimetric investigations show that the volatility of Ln(dpm)3 increases in the series from [La(dpm)3]2 to Yb(dpm)3. Melting points of the complexes are close to the known literature data.
