N2 - Two new Dawson-Type POTs, (H2en)H2[Cu(en)2][Cu(en)(H2O)3][Cu(en)2 (H2O)](P2W17CuO61)·8H2O (1, en = ethylenediamine) and H10K6(P2W17CuO61)2·34H2O (2), have been synthesized under hydrothermal conditions and characterized by IR spectroscopy, TG, XRD and single-crystal X-ray structural analysis. Crystal data for 1: triclinic, P1̄, a = 11.6855(26) Å, b = 13.2679(29) Å, c = 28.1540(60) Å, α = 80.4009(75)°, β = 82.5150(79)°, γ = 67.1482(46)°, Z = 2. Crystal data for 2: monoclinic, C2/c, a = 43.5701(99) Å, b = 12.3078(25) Å, c = 29.3742(66) Å, β = 101.3749(21)°, Z = 4. Compound 1 exhibits a 1D chain, in which the [Cu(en)2]2+ cations act as the linkages of mono-{P2W17Cu} units. Compound 2 shows a 2D layer, in which the double-Dawson units are connected by K+ cations.
