Polyoxovanadate-based organic–inorganic hybrids: from {V5O9Cl} clusters to nanosized octahedral cages†
Abstract
Three polyoxovanadate-based metal–organic polyhedra (denoted as VMOP-1, -2, and -3), adopting isostructural discrete octahedral cage geometries, were successfully synthesized under solvothermal conditions. These structures are all built up from the same pentavanadate {V5O9Cl} cluster connected by linear bidentate ligands (H2L1 = H2BDC, H2L2 = H2BDC-NH2, H2L3 = H2BDC-Br), respectively.
