The metal ions in the complexes mainly ethers are alkali and alkaliearth metal ions. Some transition metal complexes have been reported but not in large numbers. In order to reveal the structure character of this kind of compound we determined the crystal structure of （VOCl2.4H2O）（18-crown-6） by X-ray diffraction method to investigate the way of linking crown ether with vanadium.展开更多
