A new organic-inorganic hybrid phosphotungstate-based Cu ~ Ⅱ-Er ~ Ⅲ heterometallic derivative [Cu (dap) _2 (H_2O)] [Cu (dap) _2] _ (4.5) [Er (α-PW_ (11) O_ 39)) _2] · 4H 2 O (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 = A = 103.468 (4), β = 103.829 (4), γ = 98.296 (4) °, V = 6148.0 (19) 3, Z = 2, μ = 22.212 mm -1, GOOF = 1.030, R = 0.0744 and wR = 0.1700.Structural analysis indicates that 1 exhibits a special two-dimensional double-layer structure constructed from 1: 2-type [ Er (α-PW_ (11) O_ (39)) _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-PW_ (11) O_ (39)) _2] ~ (11-) moieties function as the five-connected nodes. Stillrther, its thermogravimetric behavior has been studied.
