title: Synthesis, crystal structure and photocatalytic properties of an unprecedented arsenic-disubstituted Lindqvist-type peroxopolyoxoniobate ion: {As2Nb4(O2)4O14H1.5}(4.5-).
abstract: An unprecedented arsenic-disubstituted Lindqvist-type peroxopolyoxoniobate Cs2.5Na2{As2Nb4(O2)4O14H1.5}·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.
