A novel organic-inorganic hybrid phosphovanado-molybdate Na(H2O)(6)[Cu(2,2'-bipy)(3)](2)[Cu(1,2-dap)(2)(H2O)](6)H[Cu(1,2-dap)(2){PM o(8)(vI)V(4)(Iv)O(40)((VO)-O-Iv)(2)Cu(1,2-dap)(2)}](6)center dot 2H(2)O (I) (1,2-dap = 1,2-diaminopropane, 2,2'-bipy = 2,2'-bipyridine) has been hydrothermally synthesized and characterized by elemental analyses, IR, TG-DTA, X-ray photoelectron spectroscopy (XPS), X-ray powder diffraction (XRPD). and single crystal X-ray diffraction. Interestingly, I represents the first example of cyclohexane-like ring-shaped phosphovanadomolybdate constructed from six bicapped pseudo-Keggin clusters [(PMo8V4O40)-V-vI-O-Iv((VO)-O-Iv)(2)Cu(1,2-dap)(2)](5-) linked by six [Cu(1,2-dap)(2)](2') linkers. Notably, adjacent rings are connected together, forming the 3-D supramolecular structure through hydrogen bonding interactions.
