Nona-copper(ii)-containing 18-tungsto-8-arsenate(iii) exhibits antitumor activity†
Abstract
The nona-CuII-containing tungstoarsenate(III) [H4{CuII9AsIII6O15(H2O)6}(α-AsIIIW9O33)2]8− (1a) has been synthesized and characterized. Polyanion 1a comprises a unique, cylindrical {CuII9AsIII6O15(H2O)6}6+ cluster, which forms a large central cavity and is capped on either end by an [α-AsIIIW9O33]9− capping group. It exhibits remarkable activity against K562 leukaemia cells, as well as induces HepG2 cell apoptosis and autophagy.
