title: Polyoxotungstate incorporating organotriphosphonate ligands: synthesis, characterization, and catalytic for alkene epoxidation.
abstract: A S-shaped organotriphosphonate polyoxotungstate, K4H6[H4{(AsW9O33)Zn(H2O)W5O11(N(CH2PO3)3)}2(μ2-O)2]·27H2O (1), has been synthesized and characterized. Compound 1 contains a different geometry of [{Zn(H2O)W5O19(N(CH2PO3)3)}](12-) clusters, which forms a chiral conformation. The catalysis of 1 for alkene epoxidation was investigated with a hydrogen peroxide (H2O2) oxidant.
