New polyoxometalates linked by the binder crystallize in a variety of structures with 1–3 dimensions because of transition metal coordination complexes usually serve as binders of the main metal oxide framework.
In those polyoxovanadiums, the structural motifs are usually based on edge- and cornersharing VO5 square pyramids and VO4 tetrahedra.
In the BAVAO and organic molecules systems by hydrothermal synthesis, there are some complex structures reported.
