Two new polyoxometalate-based metal-organic complexes constructed from two in-situ transformed ligands through different ways

Supramolecular cooperative interaction-induced assembly of phosphotungstate polyanions and sulfur-containing pyridine-based cations

Three crystals were assembled by means of multiple weak intermolecular cooperative supramolecular interactions of hydrogen bonding, S⋯O, C–H⋯π, and polyanion–π.

Using a flexible bis(pyrazol) ligand to construct four new Keggin-based compounds: syntheses, structures and properties

Four new Keggin-based compounds were constructed. A discrete mono-supporting structure and a supramolecular chain were obtained. Compounds 3 and 4 were formed in one pot containing either bi-nuclear cycles and nested cycle subunits.
