摘要：

合成了含有草酸根(OX)桥基的铁(Ⅲ)的配合物配体[Hpip] [(salen)FeⅢ(OX)](pip=哌啶;salen=N,N'-二水杨醛缩乙二胺),并解析了其晶体结构.利用这一含有草酸根桥基的配合物配体组装了3个新的异三核配合物[(salen)FeⅢ(μ-OX)]2[MⅡ(H2O)2]·nH2O[MⅡ=CuⅡ(1), NiⅡ(2),FeⅡ(3)],并进行了结构表征,变温磁化率(4.2~300 K)测定结果均未表现出非正规自旋态的类铁磁行为.通过计箅和分析,讨论了满足"非正规自旋态"的充分和必要条件>

Abstract:

The Fe(Ⅲ) complex with oxalate (OX) bridge [Hpip][(salen)FeⅢ(OX)] has been synthesized and the crystal structure has been determind, where pip is piperidine,salen is ethylenebis (salicylideneiminate). Three new heterotrinuclear complexes were synthesized and characterized with the molecular block,namely [(salen)FeⅢ(μ-OX)]2[MⅡ(H2O)2]·nH2O[MⅡ=CuⅡ(1), NiⅡ(2),FeⅡ(3)]. The temperature dependence of the magnetic susceptibility of the complexes were measured over the 4.2-300 K range. These results reveal antiferromagnetic, not ferroraagnetic-Jike behaviour(irregular spin state structure) for the complexes. The prerequisite and full condition for Lhe presence of irregular spin state within heterotrinuclear complexes have been discussed theoretically and experimentally.

Key words: Oxalate bridge, Heterotrinuclear complexes, Magnetic property, Irregular spin state
