通过H2 L与Ln(NO3)3·6 H2O反应,合成了4个N,N′-双水杨醛-1,2-苯二胺(H2 L)三核稀土配合物[Ln 3L 3(CH 3OH)2(NO3)3]·(CH 2Cl 2)·(CH 3OH)·(H2O)2[Ln = Tb(1),Ho(2),Er(3)和Lu(4)]。由H_2L与Nd(OAc)_3·4H_2O反应得到了一个N,N′-双水杨醛缩1,2-苯二胺双核钕配合物[Nd_2L_3(CH_3OH)](5)。X射线晶体学分析表明,配合物1 − 4是三层三核夹心结构,而配合物5是三层双核夹心结构,扩展了最近报道的多核纯镧系元素配合物。
FourN,N′-bis(salicylidene)-1,2-(phenylene-ediamine) (H2L) trinuclear lanthanide complexes, namely, [Ln3L3(CH3OH)2(NO3)3]·(CH2Cl2)·(CH3OH)·(H2O)2[Ln = Tb (1), Ho (2), Er (3) and Lu (4)], have been isolated by the reactions of H2L and Ln(NO3)3·6H2O. And oneN,N′-bis(salicylidene)-1,2-(phenylene-ediamine) dinuclear neodymium complex [Nd2L3(CH3OH)] (5) has been harvested from the reaction of H2L with Nd(OAc)3·4H2O. X-ray crystallographic analysis reveals that complexes1−4are of triple-decker trinuclear sandwich structure, while complex5is of a triple-decker dinuclear sandwich structure, expanding upon the recent reports of the multinuclear pure lanthanide complexes.
