title: Copper-organic cationic ring with an inserted arsenic-vanadium polyanionic cluster for efficient catalytic Cr(VI) reduction using formic acid.
abstract: Polyanionic cluster [β-As8V14O42(H2O)](4-) is well embedded in a large porous eight-membered cationic ring of the copper ligand, giving a stable host-guest supramolecular system. The assembly exhibits an efficient heterogeneous catalytic performance for the reduction of Cr(VI) using formic acid at ambient temperature.
