  Two new polyoxometalates [HN(C2H5)3]3[PMo12O40] (1) and [NH2(C2H4NH3)2]2[Mo5P2O23] (2) have been hydrothermally synthesized and characterized by IR, UV-Vis, XPS spectra, TG analyses, and single crystal X-ray diffraction. Crystal data for 1: monoclinic, space group C2/c, a = 24.651(5) Å, b = 10.822(2) Å, c = 22.413(5) Å, β = 120.37(3)°, and V = 5158.7(18) Å3; for 2: triclinic, space group P-1, a = 9.821(2) Å, b = 9.948(2) Å, c = 14.687(3) Å, α = 95.490(3)°, β = 98.870(3)°, γ = 95.710(3)°, and V = 1401.7(5) Å3. The crystal structure analyses reveal complex hydrogen bonds in both 1 and 2 in 3-D supramolecular arrays constructed from different polyoxoanions and organic ligands.

  Two compounds based on polyoxometalates, (4,4'-H2bpy)7(4,4'-Hbpy)[BW12VIO40]2[BW12VIO40] ·10H2O (1) and (4,4'-H2bpy)6(4,4'-bpy)[P2W18VIO62]2 · 18H2O (2), have been prepared under hydrothermal conditions and characterized by IR, XPS spectra, TG analyses, and single crystal X-ray diffraction. Both compounds consist of 4,4'-bipyridine units and polyoxometalates: [BW12VIO40]5- for 1 and [P2W18VIO62]6- for 2. In addition, 1 contains both Keggin-type and disordered Keggin-type anions, while 2 contains a (H2O)10 water cluster.
