| 摘要: 利用3，5-二氨基苯甲酸配体合成了2种新的配合物[Cd(diaba)(phen)2]NO3·H2O(1)和[Zn(diaba)(2，2’-bipy)2](2)(H2diaba=3，5-diaminobenzoicacid；phen=1，10-phenanthroline，2，2’-bipy=2，2’-bipyridine)，并对其进行了元素分析、红外光谱和X射线单晶衍射测定。配合物1属于正交晶系，空间群为Fddd，a=1.42581(7)nm，b=2.56462(13)nm，c=3.09247(17)nm。配合物2属于单斜晶系，空间群为C2/c，a=1.27362nm，b=1.59278nm，c=1.51935nm，β=107.334°。配合物1和2都为单核晶体。配合物1的结构单元由1个CdⅡ、1个3，5-二氨基苯甲酸和2个phen构成。配合物2的结构单元由1个ZnⅡ、1个3，5-二氨基苯甲酸和2个2，2’-bipy构成。两种配合物再通过氢键或π-π堆积形成三维超分子网络。研究了配合物的热稳定性和荧光性质。 | |

| Abstract: The title complexes, [Cd(diaba)(phen)2] NO3·H2O(1) and [Zn(diaba)(2,2'-bipy)2](2) (diaba=3,5-diaminobenzoic acid; phen=1,10-phenanthroline, 2,2'-bipy=2,2'-bipyridine), has been synthesized by hydrothermal reactions and characterized by IR, TG, fluorescent spectrum and single-crystal X-ray diffraction techniques. The structure indicates that the complex 1 crystallizes in orthorhombic, space group Fddd with a=1.42581(7) nm, b=2.56462(13) nm, c=3.09247(17) nm. The structure indicates that the complex 2 crystallizes in monoclinic, space group C2/c with a=1.27362 nm, b=1.59278 nm, c=1.51935 nm, β=107.334°. The crystal structure of complex 1 consists of one CdⅡ, one 3,5-diaminobenzoic acid ligand and two phen ligands. The crystal structure of complex 2 consists of one ZnⅡ, one 3,5-diaminobenzoic acid ligand and two 2,2'-bipy ligands. In two complexes, the adjacent mononuclear molecular recognize each other to generate a 3Dsupramolecular structure via the hydrogen bonding or the π-π stacking interaction. In additional, thermal stability and photoluminescence properties of two complexes have also been studied. | |
