摘　　要：本工作合成了N—水杨酰基二茂铁乙酮腙的La(Ⅲ)等六种配合物,通过元素分析,IR,UV,TG—DTA和摩尔电导研究了它们的组成和性质。结果表明,配体在配合物中是以“酮式”存在,以酰胺基的氧原子和亚胺基的氮原子与稀土金属(Ⅲ)配位。组成有M(HL)_3(M=La和Nd)和M(HL)_2(M=Y.Th,Gd和Pr)两种形式。Th(HL)_2·(NO_3)_3是1:2型电解质,其余配合物属于1:1型。The coordination compounds of N—salicyloylacetoferrocenoyl hydrazone with La (Ⅲ), Nd(Ⅲ), Y(Ⅲ), Th(Ⅳ), Gd(Ⅲ)and Pr(Ⅲ)are synthesized in this paper, and their composition, physical and chemical properties are studied by their elemental analysis, IR, UV, TG—DTA and Molar Gconductance. The results show that the ligand, which exists as'keto—form' in the coordination compounds, corrdinates rare earth metals(Ⅲ) through zaomethine nitrogen and amide oxygen. Thc composition have tw forms, M (HL)_3 (M=La and Nd)and M (HL)2 (M=Y, Th, Gd and Pr). Th(HL)_2(NO_3)_3 is 1:2 type electrolyte, the other coordination compounds are 1:1 type.
