| 摘要: 合成了4个含双水杨醛Schiff碱配体的双核过渡金属配合物,并通过元素分析、红外光谱、紫外光谱,热重分析以及X-射线单晶衍射等手段对所得配合物进行了表征。结果表明,配合物1、3和4都属于三斜晶系,空间群为P1,而配合物2属于单斜晶系,空间群为C2/c。在配合物1中,2个Cu(Ⅱ)离子具有不同的配位构型,其中一个Cu(Ⅱ)形成了五配位的四角锥构型,而另一个Cu(Ⅱ)形成了平面正方形构型。配合物4中,通过酚氧原子的桥联作用,双核单元相互连接形成了一维链状结构。 |

| Abstract: Four dinuclear transition metal complexes with schiff base ligand of bis-salicylaldehyde have been synthesized and structurally characterized by means of elemental analysis, IR, UV, TGA and X-ray single-crystal diffraction. The results of structural analysis indicate that complex 1, 3 and 4 belong to triclinic crystal system, space group P1 and the complex 2 belong to monoclinic crystal system, space group C2/c. In complex 1, two copper ions show different coordination environment, one of which has a five-coordinate, slightly distorted tetragonal pyramidal geometry and another has a four-coordinate squareplanar geometry. In complex 4, the binuclear units are held together to form an infinite 1D chain by bridging phenol O atoms. |
