摘要
合成了双水杨醛缩乙二胺Ｓｃｈｉｆ碱（ＳＡＬＥＮ）与钴的配合物Ｃｏ（ＳＡＬＥＮ）（ＮＯ３）２·３Ｈ２Ｏ及镧系－钴的异核配合物ＬｎＣｏ（ＳＡＬＥＮ）２（ＮＯ３）５·２Ｈ２Ｏ（Ｌｎ＝Ｌａ，Ｎｄ，Ｓｍ，Ｇｄ，Ｙｂ，Ｙ）．以紫外、红外光谱，特别是１ＨＮＭＲ及ＥＰＲ波谱等方法研究了它们在组成、结构和配位等方面的异同．文中讨论了配合物ＥＰＲ谱在不同溶剂中峰宽的相对关系、配合物晶体场强度及Ｇｄ３＋周围局部对称性等问题．
A series of heteronuclear Ln(Ⅲ) Co(Ⅱ) and Co(Ⅱ) complexes with bis salicylaldehyde ethylenediamine(SALEN) have been synthesized. They were characterized as LnCo(SALEN) 2(NO 3) 5·2H 2O(Ln=La,Nd,Sm,Gd,Yb,Y) and Co(SALEN)(NO 3) 2·3H 2O respectively. The differences between their compositions, structures and coordinations have been investigated by UV, IR, especially by 1H NMR and EPR spectra. The EPR spectra of the GdCo(SALEN) 2(NO 3) 5·2H 2O complex in powder and various solvents at different temperatures and the “U” spectral feature, crystal field strength and local symmetry around Gd 3+ have been discussed.
