摘要：
The structure of two lanthanide (Ln = Nd, Ho) complexes with dipivaloylmethane (Hdpm) is studied at 150(2) K by single crystal X-ray diffraction. The crystallographic data are as follows for [Nd(dpm)3]2: space group P21/n, a = 12.3281(3) Å, b = 27.8118(6) Å, с = 21.9035(5) Å, β = 105.241(1)°, V = 7245.8(3) Å3, Z = 4, R = 0.0333; for [Ho(dpm)3]2: space group P21/n, a = 12.2067(6) Å, b = 27.5626(13) Å, с = 21.8624(10) Å, β = 105.188(1)°, V = 7098.6(6) Å3, Z = 4, R = 0.0321. Both structures are molecular and consist of neutral [Ln(dpm)3]2 dimeric molecules. The thermogravimetric studies demonstrate that Ln(dpm)3 volatility increases in the series from [La(dpm)3]2 to Yb(dpm)3.
