Synthesis, structures, and magnetic properties of metal–organic polyhedra based on unprecedented {V7} isopolyoxometalate clusters†
Abstract
Two isostructural vanadium-based metal–organic polyhedra (denoted as VMOP-16 and VMOP-17) were synthesized by a solvothermal method, which are built from unprecedented {V7} isopolyoxometalate clusters and dicarboxylate ligands. To our knowledge, the {V7} second building unit is reported for the first time and features the highest nuclearity of vanadium–oxygen clusters compared with reported vanadium-based MOPs.
