Abstract: In this paper, the two coordination compounds of copper perchlorate with 4′-bromo(or 4′,5′-dibromo)-benzo=15-crown-5 have been prepared in acetone medium, the composition of the new coordination compounds have been determined as Cu(ClO4)2·L·3H2O(L=4′-bromobenzo-15-crown-5 or 4′, 5′-dibromo-benzo-15-crown-5), the IR, UV, TG-DTA,X-ray powder diffraction analysis and molar conductance of these coordination compounds have also been studied. It shows that coordination number of the coordination compounds is 9.

Key words: copper perchlorate, crown ether, coordination compound
