Preparation And Characterization Of Bridgibg Complexs Of Cobalt Cluster And Rare Earth

The preparation route of the cluster (CO)₆Co₂HCCCOOH was improved, and its yield and purity was increased. Cluster (CO)₁₀Co₄HCCCOOH was designed as the starting material for this research, however, this oxygen- sensitive cluster is difficult to be obtained in high yield and the preparation route needs to be improved. Some efforts have been made, but the work needs to be continued further. A novel europium ternary complex Eu(Phen)(HCCCOO^-)₂(ClO₄^-).C₂H₅OH (phen is phenanthrolme) was synthesized and characterized by IR, element analysis, ¹HNMR and fluorescent spectroscopy. This complex can not be used to prepare the designed target complex due to its poor solubility, but it is worthwhile to studying the fluorescent property because of its relative high fluorescent intensity. A bridging complex...
