Abstract

An organic–inorganic hybrid phosphotungstate-based CuII–LaIII heterometallic derivative [Cu(dap)2(H2O)][Cu(dap)2]4.5 [La(α-PW11O39)2].4H2O (1) (dap = 1,2-diaminopropane) has been prepared and characterized by elemental analysis, IR spectra, UV spectrum, optical diffuse reflectance spectrum, thermogravimetric analysis, and X-ray crystallography. Complex 1 exhibits a 2-D CuII–LaIII heterometallic sheet architecture with a 4-connected topology established by dimeric [Cu(dap)2(H2O)]2[Cu(dap)2]9[La(α-PW11O39)2]2 building units via [Cu(dap)2]2+ bridges. The optical diffuse reflectance spectrum indicates that 1 possesses the semiconductor characteristic. The thermogravimetric curve of 1 shows two steps of weight loss.
