A novel 2-D organic-inorganic hybrid copper-yttrium heterometallic monovacant Keggin phosphotungstate derivative [Cu(dap)(2)](5.5)[Y(alpha-PW11O39)(2)]center dot 4H(2)O (1) (dap = 1,2-diaminopropane) has been hydrothermally synthesized by reaction of Na-9[A-alpha-PW9O34]center dot 7H(2)O, CuCl2 center dot 2H(2)O, YCl3 and dap and structurally characterized by elemental analysis, IR spectrum, UV spectrum, powder X-ray diffraction (PXRD), and X-ray single-crystal diffraction. 1 illustrates an interesting 2-D copper-yttrium heterometallic sheet architecture with a 5-connected topology built by 1:2-type [Y(alpha-PW11O39)(2)](11-) subunits and [Cu(dap)(2)](2+) bridges. To our knowledge, 1 represents a rare 2-D organic-inorganic hybrid Keggin phosphotungstate-based transition metal and rare-earth heterometallic derivative. The photocatalytic measurements show that 1 can inhibit the photodegradation of rhodamine-B.
