Abstract :Five new Anderson-type polyoxometalate compounds [Minsert ignore into journalissuearticles values(insert ignore into journalissuearticles values(1,10-phen);insert ignore into journalissuearticles values(OH);x]3[Crinsert ignore into journalissuearticles values(OH);6Mo6O18]∙16H2O insert ignore into journalissuearticles values(M=Crinsert ignore into journalissuearticles values(1);, Mninsert ignore into journalissuearticles values(2);, Coinsert ignore into journalissuearticles values(3);, Niinsert ignore into journalissuearticles values(4);, Cuinsert ignore into journalissuearticles values(5);; x=1,2); were obtained from Na2MoO4∙2H2O and CrCl3∙6H2O within acidic aqueous medium insert ignore into journalissuearticles values(pH=2-3);. The compounds are characterized by means of FT-IR, TGA, ICP-MS, and elemental analysis techniques. The structural analysis show that compounds insert ignore into journalissuearticles values(1-5); consist of a Anderson-type polyanion [Crinsert ignore into journalissuearticles values(OH);6Mo6O18]3-.
