摘要
根据文献合成DBrB15C5和BrNO_(2)B15C5化合物,以此配体与氯铂酸作用,得到两种固体配合物,测试其物理化学性质。比较了B15C5、BrB15C5、DBrB15C5、BrNO_(2)B15C5与氯铂酸生成的固态配合物的热稳定性,讨论了冠醚苯环上吸电子取代基团的增加对配合物热稳定性的影响。
The syntheses and properties of a new kind crown ether solid coodination complexes of chloroplatinic acid with 4',5'-二Br-Benzo-15-Crown-5 and 4'-Br-5'-NO_2-Benzo-15-Crown-5 are studied and identified by element analysis, IR spectrum, UV spectrum and TG-DTA. Their thermal behavior are also investigated.The effect of the attracting electron substituents on crown ether on the thermal stabilities of the complexes is discusscd.
