摘　　要：以2-(4-噻唑基)苯并咪唑(HTBZ)配体和二价铁离子为原料,采用水热法合成得到了一种新颖的二价铁配合物[Fe(TBZ)(HTBZ)_(2)]ClO_(4)(1)。通过X射线单晶衍射仪确定了其结构,采用元素分析、红外光谱和热重分析等手段进行了表征。对晶体结构进行分析后可知,配合物1属于三方晶系,R-3c空间群。该配合物结构中,HTBZ/TBZ-配体采用双齿螯合配位模式与二价铁离子配位,形成以[Fe(TBZ)(HTBZ)_(2)]ClO_(4)为单元的零维单核结构。变温磁化率测试研究表明该配合物在2~300 K范围都是顺磁的。A novel coordination compound,namely,[Fe(TBZ)(HTBZ)_(2)]ClO_(4)(1) was synthesized by using 2-(4-thiazolyl)benzimidazole(HTBZ)as ligand and Fe(Ⅱ)ions under hydrothermal conditions.The structure was confirmed by X-ray single crystal diffractometer,and it was characterized by elemental analysis,infrared spectroscopy and thermogravimetric analysis.The results show that it crystallizes in the trigonal crystal system and the R-3c space group.The HTBZ/TBZligand coordinated to the Fe(Ⅱ)ion with a bidentate chelate coordination mode,forming a zero-dimensional structure based on[Fe(TBZ)(HTBZ)_(2)]ClO_(4) building units.Variable temperature magnetic susceptibility studies show that the complex is paramagnetic in the range of 2~300 K.
