摘要：

On the basis of infrared spectra and comparison with spectra of known crystalline structures of V2O5, ZnV2O6, CdV2O6, Zn2V2O7 and Cd2V2O7, it is shown that the basic structural units in zinc vanadate and cadmium vanadate glasses are unmodified VO5 groups, modified VO5 groups and V2O7 pyrovanadate units. SbO3 deformed pyramids are the main structural units in the network of antimony vanadate glasses with high Sb2O3 content. Different structural models are developed for these vanadate glasses.
