Abstract

Four types of organic–inorganic hybrids Na[Cu(en)2(H2O)]4[Cu(en)2]2[Cu(H2O)4]0.5{Cu(en)2[H2CeIV(α-AsW11O39)2]2}·10H2O (1), Na3[Cu(en)2(H2O)][Cu(en)2]1.5[H3Ln(α-AsW11O39)2]·xH2O [Ln = PrIII, x = 5 (2); Ln = NdIII, x = 4.5 (3); Ln = SmIII, x = 5.5 (4); Ln = EuIII, x = 4 (5); Ln = TbIII, x = 4 (6)], [Cu(dap)(H2O)2]0.5[Cu(dap)2(H2O)]2[Cu(dap)2]3[Ln(α-AsW11O39)2]·xH2O [Ln = PrIII, x = 3 (7); Ln = EuIII, x = 3 (8)] and [Cu(dap)2]5.5[Ln(α-AsW11O39)2]·xH2O [Ln = TbIII, x = 6 (9); Ln = DyIII, x = 5 (10)] (en = ethylenediamine, dap = 1,2-diaminopropane) have been hydrothermally synthesized and fully characterized by elemental analyses, IR spectra, solid-state UV spectra, powder X-ray diffraction (PXRD) and single-crystal X-ray diffraction. 1 exhibits the first 2D TM–Ln heterometallic sheet architecture with a 4-connected topology established by tetrameric [Cu(H2O)4{Cu(en)2[H2Ce(α-AsW11O39)2]2}2]26− units via [Cu(en)2]2+ bridges. 2–6 are isomorphic and display the unique 2D (6,3)-network topology constructed from 1 : 2-type [H3Ln(α-AsW11O39)2]8− units through [Cu(en)2]2+ linkers. 7–8 represent the first 1D “dendritic” chain-like TM–Ln heterometallic POMs based on the 1 : 2-type [Ln(α-AsW11O39)2]11− units. 9–10 are the unique 2D sheets built by 1 : 2-type [Ln(α-AsW11O39)2]11− units and [Cu(dap)2]2+ connectors, in which the [Ln(α-AsW11O39)2]11− subunits act as 5-connected nodes and adjacent 2D sheets are packed in the mode of –AAA–. The photocatalytic measurements show that 1–10 can to some extent inhibit the photodegradation of rhodamine-B (RhB). Moreover, the luminescence properties of 5–6 and 8–9 have been investigated.
