摘 要:以琥珀酸二甲酯、水合肼、2-苯甲酰吡啶,N i(NO3)2.6H2O为原料,在无水甲醇中合成双核镍配合物,其结构经X-射线单晶衍射仪表征,每个镍离子配位于来自两个配体的两个吡啶酰肼单元,两个镍离子通过两个丁二酸单元桥联,金属间距分别为5.957。对此配合物进行X-射线粉末衍射分析,选择2θ为5~30,与其拟合图对比证明此为N i2+配合物。热重分析显示配合物随温度的升高逐渐失重,至200℃失去甲醇分子,至365℃配体完全分解,大约失重65%。In Dimethyl Succinate,hydrazine hydrate and Ni(NO3)2·6H2O as raw materia,in anhydrous methanol synthesis dual-core nickel complexes,its structure by X-ray diffraction instrument monocrystal duty,every nickel ions are respectively from two ligands in the two pyridine hydrazide unit,and two nickel ions are union bridge by two succinic acid,where those metal spacing are both 5.957 .On this complexes powder X-ray single crystal structure analysis,we select angle 3-50,instead of fitting graph compares proof this for Ni2 + complexes.Thermogravimetric analysis shows that the complexes are weightlessness while temperature rise gradually.Up To 200℃,methanol molecules are losed,and to 365℃,the ligands are complete decomposed,and lose their weigh about 65%.
