Abstract: This paper reports the syntheses and properties of the coordination compounds of CoCl2 with dibenzo-24-crown-8, dibcnzo-30-crown-10, 4'-iodobcnzo-15-crown-5 and 4'-bromobenzo-15-crown and the coordination compounds of Co(NO3)2 with benzo-15-crown-5,4'-iodobenzo-15-crown-5 and 4'-bromobcnzo-15-crown-5. The complexes have been characterized by elemental analysis, IR, UV, DTA-TG and X-ray powder diffraction analysis as well as the molar conductance measurements.

Key words: cobalt chloride, cobalt nitrate, crown ether, coordination compound, synthesis
