摘要
A new organic-inorganic hybrid phosphotungstate-based Cu^Ⅱ-Er^Ⅲ heterometallic derivative[Cu（dap）2（H2O）][Cu（dap）2]4.5[Er（α-PW11O39）2]·4H2O（1,dap = 1,2-diaminopropane） has been hydrothermally prepared and characterized by elemental analysis,IR spectra and X-ray single-crystal diffraction.1 belongs to the triclinic space group P1 with a = 13.453（3）,b =20.137（4）,c = 24.565（4） A,α = 103.468（4）,β = 103.829（4）,γ = 98.296（4）°,V= 6148.0（19） A°3,Z =2,μ = 22.212 mm^-1,GOOF = 1.030,R = 0.0744 and wR = 0.1700.Structural analysis indicates that1 exhibits a special two-dimensional double-layer structure constructed from l：2-type[Er（α-PW11O39）2]^11- moieties and[Cu（dap）2]^2＋ linkers.From the topological viewpoint,1 displays a scare two-dimensional five-connected topology in which the[Er（α-PW11O39）2]^11- moieties function as the five-connected nodes.Furthermore,its thermogravimetric behavior has been studied.
