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(Cl O4)2或Mn Cl2·4H2O分别与该配体在溶液中反应生成了一个四核锰簇合物[Mn III4(HL)2(H2L)2(Me CN)4](Cl O4)2·2Me CN(1)和一个十核锰簇合物[Mn III6MnII4(bz)10(L)4(H2O)2]·10Me CN(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。
A multidentate salicylaldehyde Schiff base ligand with 3,5-di-tert-butylsalicylaldehyde-tris (hydroxymethyl) aminomethane (H4L) with {NO4} electron donor was synthesized and characterized by elemental analysis , Infrared spectroscopy and nuclear magnetic resonance spectroscopy to characterize its structure. Mn (ClO4) 2 or Mn Cl2 · 4H2O react with the ligand in solution respectively to form a tetranuclear manganese cluster [Mn III4 (HL) 2 (H2L) 2 (Me CN) 4] (Cl O4) 2 · 2Me CN (1) and one decagonal manganese cluster [Mn III6MnII4 (bz) 10 (L) 4 (H2O) 2] · 10Me CN (2). X-ray diffraction analysis showed that the crystal structure space group of compound 1 was triclin P1, while the magnetic measurement data of compound 2 at an orthogonal Aba2.2-300 K temperature range indicated that there was an antiferromagnetic interaction in compound 2.
