合成了高氯酸钴、高氯酸锌与4′,5′-二溴苯并-15-冠-5固态配合物和高氯酸铜与4′-NO_2-5′-Br-苯并-15-冠-5固态配合物.通过元素分析、红外光谱、紫外光谱、摩尔电导、X-射线粉末衍射分析,研完了其有关的物化性质,证明3种配合物均为1∶1型配合物.

The new solid coordination compounds of cobalt perchlorate,zinc perchlorate with 4′,5′-dibromobenzo-15-crown-5(Br_2B_(5)C_5),and the solid coordination compound of cop- per perchlorate with 4′-bromo-5′-nitrobenzo-15-crown-5(BrNO_2B_(5)C_5)having the composi- tions M(ClO_4)_2·Br_2B_5C_5·1/4(CH_3)_2CO·5/2H_2O(M=Co,Zn)and Cu(ClO_4)_2·BrNO_2B_(5)C_5· 2H_2O were synthesized in acetone and benzene-propanol(1:1).All the complexes are charac- terized by elemental analysis,IR and UV spectra,as well as X-ray powder diffraction analy- sis.According to the IR spectra the ClO_4^- anions are not coordinated.These complexes are proved to be 1:2 electrolytes by conductance measurement in acetonitrile solution.
