• 1-D and 2-D inorganic–organic hybrid polyoxomolybdates
• Organic–inorganic hybrid octamolybdates
• The photocatalytic degradation towards rhodamine-B
Two new 1-D and 2-D inorganic–organic hybrid polyoxomolybdates [H2dap]2[x-Mo8O26]·2H2O (1) and [Cu(dap)2]2[β-Mo8O26] (2) (dap = 1,2-propanediamine) have been hydrothermally synthesized and structurally characterized by elemental analyses, IR spectra, powder X-ray diffraction and single-crystal X-ray diffraction. The most remarkable structural differences between them are that 1 displays a 1-D chain constructed from [x-Mo8O26]4 − clusters through two terminal O atoms from adjacent [x-Mo8O26]4 − clusters whereas 2 demonstrates the 2-D extended layer made up of [β-Mo8O26]4 − clusters via [Cu(dap)2]2 + connectors. To our knowledge, the [x-Mo8O26]4 − cluster in 1 is reported for the first time. The thermogravimetric (TG) curve of 1 shows a two-step weight loss whereas the TG decomposition of 2 only proceeds in one stage. Additionally, their electrochemical behaviors and their photocatalytic degradation properties towards rhodamine-B are also investigated.
