| 摘 要： | 合成了一种具有{NO4}给电子组成的多齿水杨醛希夫碱配体,3,5-二-叔丁基水杨醛-三(羟甲基)氨基甲烷(H4L),并利用元素分析、红外光谱以及核磁共振氢谱表征其结构。Mn(ClO4)2或MnCl2·4H2O分别与该配体在溶液中反应生成了一个四核锰簇合物[MnIII4(HL)2(H2L)2(MeCN)4](ClO4)2·2MeCN(1)和一个十核锰簇合物[MnIII6MnII4(bz)10(L)4(H2O)2]·10MeCN(2)。X-射线衍射分析表明化合物1的晶体结构空间群为三斜P1,而化合物2为正交Aba2。2~300 K温度区间的磁性测量数据表明化合物2中存在反铁磁相互作用。

| Abstract: | A multidentate salicylaldehyde Schiff-base ligand with {NO4} donor set, 3, 5-di-tert-butylsalicylaldehyde-trihydroxymethylaminomethane (H4L), has been synthesized for the first time and characterized by elemental analysis, IR and 1H NMR. Solution reactions of Mn(ClO4)2 or MnCl2·4H2O with H4L in air generated a tetranuclear complex [MnIII4(HL)2(H2L)2(MeCN)4](ClO4)2·2MeCN (1) and a decanuclear complex [MnIII6MnII4(bz)10(L)4(H2O)2]·10MeCN (2), respectively. X-ray studies reveal that complex 1 crystallizes in triclinic space group P1, while complex 2 crystallizes in orthorhombic space group Aba2. Magnetism data in the temperature range 2~300 K have been carried out, indicating the presence of the antiferromagnetic interaction within 2. |
