| Abstract: | A new two-dimensional (2D) purely inorganic 4d-4f heterometallic compound La(H2O)8]Ag{La(H2O)6}2{SiW11La(H2O)4O39}2]·13H2O (1), based on mono-lacunary Keggin-type {α-SiW11O39} cluster (abbreviated to SiW11), was conventional synthesized and characterized by elemental analysis, IR, TG, and single crystal X-ray diffraction. In compound 1, two mono-substituted {SiW11La(H2O)4O39}2 clusters (abbreviated to SiW11La) polymerize together to form a dimer. And the dimers are linked by Ag+ and La3+ heterometallic cations displaying a 2D network. Furthermore, the photocatalytic experiment indicates that the title compound presents excellent photocatalytic activity towards degradation of rhodamine B (RhB) dye. |
