摘 要: | Interest in polyoxometalates is expanding rapidly due to the enormous variety of structure topologies leading to interesting and unexpected properties in such diverse field as catalysis, materials science and medicine1-4. Frameworks constructed from square pyramidal, octahedral, tetrahedral units are well documented in the solid-state phases of the V/O/P system5. For the heteropolyanions class of clusters, the V/O/As system has been extensively studied, but the linking of arsenic-vanadium …
