摘要：

Ag0.33V2O5 and Cu0.76V2O5 were obtained by heating equimolar mixtures of AgI + V2O5 (700-degrees-C) and CuI + V2O5 (525-degrees-C), respectively, in sealed quartz glass ampoules. In each case, one of the well-formed crystals served for an X-ray structure analysis. Ag0.33V2O5 has the structure known of the beta phase of the vanadium bronzes, i. e. layers of edge-sharing, distorted VO6 octahedra are liked by certain common octahedron vertices, the Ag atoms randomly occupy two positions with occupation probabilities of 0.5. CU0.76V2O5 has the previously determined structure of the epsilon phase, however, its space group is not cm hut C2/m.
