报道了自合成的 3种含 L n3 +的二聚物晶体 N d2 ( CH3 COO) 4( ONO2 ) 2 ( C12 H8N2 ) 2 ( A) ,Sm2 ( C6H5COO) 6( C12H8N2 ) 2 ( B) ,Eu2 ( C6H5COO) 6( C12 H8N2 ) 2 ( C)的 U V -VIS-NIR光谱数据 ,依据 L n3 + 能级图以及相应光谱项和选律 ,对各谱带进行了分析指认 ,并通过与 L n3 + 离子和简单化合物 L n( NO3 ) 3 · 6H2 O光谱的对比 ,讨论了配位场对二聚物中L n3 +的 f-f跃迁影响 .
We report three kinds of self-synthesized N d2 (CH3 COO) 4 (ONO2) 2 (C12 H8N2) 2 (A), Sm2 (C6H5 COO) 6 (C12H8N2) 2 (C12H8N2) 2 (C). The bands were analyzed and identified according to the Ln3 + energy level diagram and the corresponding spectral items and selection rules. + Ions and the simple compound Ln (NO3) 3.6H2O, we discuss the effect of the ligand field on the ff transition of Ln3 + in the dimer.
