Abstract

An unprecedented arsenic-disubstituted Lindqvist-type peroxopolyoxoniobate Cs_2.5Na₂{As₂Nb₄(O₂)₄O₁₄H_1.5}·11H₂O has been successfully synthesized and characterized. The photocatalytic activity of the cluster for H₂ evolution from water is investigated by irradiating with a 300 W Xe lamp, which shows a certain photocatalytic water splitting activity.
