摘要
通过溶剂热法合成了一种基于吡啶-2-甲醛肟(Hpyco)配体和吡啶-2-甲酸(Hpa)配体的配合物[Ni2(Hpyco)2(pa)(EtOH)Cl3](1),并用元素分析、红外光谱、X-射线单晶衍射对化合物的结构进行了表征。晶体属单斜晶系,P21/c空间群。晶体结构中2个Ni(Ⅱ)离子通过1个以μ1,1方式配位的氯原子和1个以μ1,1连接的羧酸氧原子桥联。配合物1的低温磁化率测定结果表明,Ni(Ⅱ)…Ni(Ⅱ)之间存在铁磁相互作用。
A complex of the composition [Ni2(Hpyco)2(pa)(EtOH)Cl3](1)(Hpyco=pyridine-2-carbaldehyde oxime;Hpa=2-picolinic acid) has been synthesized via solvothermal synthetic method,and fully characterized by X-ray single crystal diffraction,IR and elemental analysis.Crystal structure analysis revealed that 1 contains carboxylic oxygen atom bridged and chloro bridged dinuclear core with each Ni(Ⅱ),ion displaying pseudo-octahedron geometry.Low-temperature magnetic susceptibility measurement for the solid sample of 1 revealed the ferromagnetic Ni(Ⅱ),…Ni(Ⅱ),interactions.
