Abstract

A novel 2-D organic–inorganic hybrid copper-yttrium heterometallic monovacant Keggin phosphotungstate derivative [Cu(dap)2]5.5[Y(α-PW11O39)2]·4H2O (1) (dap = 1,2-diaminopropane) has been hydrothermally synthesized by reaction of Na9[A-α-PW9O34]·7H2O, CuCl2·2H2O, 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(α-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.
