【摘要】 以2,2′-二硫代二苯甲酸、2,2′-联吡啶、咪唑、硝酸锌和硝酸锰为原料,使用水热方法合成了配合物[Zn(EBLA)(2,2′-bipy)(H2O)](EBLA=2,2′-二苯甲酸硫醚)(2,2′-bipy=2,2′-联吡啶)(1),自然挥发法制备了配合物[Mn(EBSA)(im)2(H2O)]n(EBSA=2,2′-二硫代二苯甲酸)(im=咪唑)(2)。利用元素分析、红外和热重分析对其进行了表征。利用X-射线单晶衍射对结构进行了测定,并研究了配合物1的荧光性质。配合物1中,2,2′-二苯甲酸硫醚是通过水热方法由2,2′-二硫代二苯甲酸发生原位反应制备,Zn2+离子是五配位的四角锥双核结构;配合物2中,Mn2+离子是六配位的变形八面体一维链状结构。配合物中存在氢键和π-π堆积等弱的分子间作用力。
【Abstract】 Two coordination polymers [Zn(EBLA)(2,2′-bipy)(H2O)](1) and [Mn(EBSA)(im)2(H2O)]n(2) were synthesized by hydrothermal and evaporation methods using 2,2′-dithiosalicylic acid(EBSA), 2,2′-dipyridyl,imidazole, Zn(NO3)2·6H2O and Mn(NO3)2·4H2O. And the complexes were characterized by elemental analysis, FTIR and thermogravimetrie analysis(TGA), meanwhile the crystal structures and fluorescence properties of the complex 1 have been studied. In complex 1, 2,2′-dicarboxydiphenylthioether(EBLA) was prepared with 2,2′-dithiosalicylic acid(EBSA) in situ reaction by hydrothermal method. The complex 1 is a dinuclear structure and Zn2 +ion is five-coordination in a distorted square pyramidal geometry; The complex 2 is a one-dimensional infinite linear chain and Mn2+ion is six-coordination in a distorted octahedral geometry. Hydrogen bonding and π-π interactions are observed in these complexes.
