摘要：

The peroxo complex of vanadium(V) of composition CymH(2)[V2O2(O-2)(4)H2O].2H(2)O, where Cym is 5,5,7,12,12,14-hexa-methyl,1,4,8,11-tetraazacyclotetradecane, was prepared by crystallization from a water-ethanol solution of vanadium pentoxide, hydrogen peroxide and Gym. The X-ray structure analysis revealed a dinuclear structure of the complex anion with two coordinatively non-equivalent vanadium atoms bridged by a tridentate eta(2)-peroxo ligand. The compound is the thermally most stable peroxo complex of vanadium(V) of this type. After simultaneous release of active oxygen and three water molecules at temperatures up to 90 degrees C, the anhydrous metavanadate CymH(2)(VO3)(2) is formed. (C) 1997 Elsevier Science Ltd.
