自从Ｐｅｄｅｒｓｏｎ［１］发现冠醚可以和碱金属盐形成配合物以来，已有许多种金属和冠醚配合物的报道，但有关冠醚和过渡金属锰（Ⅱ）形成配合物的报道较少［２～４］．我们通过实验发现，冠醚可以和硫氰酸盐溶液中的锰（Ⅱ）形成配合物并被萃取入有机相．现就不同种类...
Since Pederson [1] discovered that crown ethers can form complexes with alkali metal salts, there are many reports of metal and crown ether complexes, but there are few reports about the formation of complexes between crown ethers and transition metal manganese [II] 2 ~ 4]. We experimentally found that crown ethers can form complexes with manganese (II) in thiocyanate solution and are extracted into the organic phase. Now different types ...
