摘　　要：采用溶液挥发法,以N^(3)-(4-吡啶基)-4-羟基苯甲酰腙(HL)为配体,制备出一例单核钴配合物[Co(HL)_(2)(CH_(3)OH)_(2)]·(NO_(3))_(2)·CH_(3)OH(1)。通过元素分析、傅立叶红外光谱、X射线粉末衍射、磁性测试等手段对配合物1进行了系统的表征。对配合物1进行了X射线单晶衍射测试,结果表明配合物1具有单核结构,属于正交晶系,C 2221空间群。每个六配位的CoⅡ离子周围有两个HL双齿螯合配位和两个甲醇分子单齿配位;构型计算表明六配位的CoⅡ离子构型为畸变的八面体结构。此外,对配合物1进行了直流场磁化率测试,结果表明配合物1存在分子间反铁磁耦合作用。A mononuclear cobalt complex[Co(HL)_(2)(CH_(3)OH)_(2)]·(NO_(3))_(2)·CH_(3)OH(1)has been successfully synthesized by the solvent evaporation method on the basis of ligands N^(3)-(4-pyridyl)-4-hydroxybenzoylhydrazone(HL).Complex 1 was systematically characterized by elemental analysis,fourier transform infrared spectroscopy,X-ray diffraction and magnetic property measurement system.The single crystal X-ray diffraction of complex 1 showed that 1 has a mononuclear structure which crystallizes in orthorhombic space group(C 2221).There are two HL bidentate ligands and two methanol monodentate ligands around each of the six-coordinated CoⅡion.The configuration calculation showed that the six-coordinated CoⅡion has a distorted octahedron configuration.In addition,the direct-current magnetic susceptibility showed that 1 exists antiferromagnetic coupling interaction.
