The complexes (N(4444))(3)[Ln(dcnm)(6)] (Ln = La-Nd, Sm; N(4444) = tetrabutylammonium) display a decrease in the melting point upon fast cooling from a melt, which is shown by in situ synchrotron based X-ray powder diffraction to be due to the formation of a second, less thermodynamically stable, polymorph.
复合物 (N(4444))(3)[Ln(dcnm)(6)](Ln = La-Nd,Sm;N(4444) = 四丁基铵)在从熔体快速冷却时表现出熔点降低的现象,这是通过基于同步辐射的原位 X 射线粉末衍射表明是由于形成了第二种热力学上不太稳定的多晶型物所致。
