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髤离子具有不同的配位构型,其中一个Cu髤形成了五配位的四角锥构型,而另一个Cu髤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。
Four binuclear transition metal complexes containing Schiff base ligands were synthesized and their structures were characterized by elemental analysis, IR, UV, TG and X-ray single crystal diffraction . The results show that the complexes 1, 3 and 4 all belong to the triclinic system, the space group is P1, while the complex 2 belongs to the monoclinic system with space group C2 / c. In complex 1, two Cu 髤 ions have different coordination configurations. One Cu 髤 forms a pentacoordinated pyramid and the other Cu 髤 forms a planar square. In complex 4, through the bridging effect of phenolic oxygen atoms, the binuclear units are connected to each other to form a one-dimensional chain structure.
