Abstract

Two new hybrid compounds, [Co(4,4′-bpy)2(H 2O)4][(4,4′-bpyH2]2[CoW 12O40]·8H2O (1) and [Fe(2,2′-bpy) 3]3[H2W12O40] ·6H2O (2), (4,4′-bpy = 4,4′-bipyridine, 2,2′-bpy = 2,2′-bipyridine) have been hydrothermally synthesized. These solids were characterized by elemental analysis, thermogravimetric analysis, UV-Vis spectroscopy and X-ray diffraction. The hydrogen-bonding interactions in 1 lead to the formation of a three dimensional network consisting of [CoW12O40]6- anionic clusters, [Co(4,4′-bpy)2(H2O)4]2+ cations and lattice water molecules, while the discrete Keggin ion [H 2W12O40]6- in compound 2 is surrounded by 14 [Fe(2,2′-bpy)3]2+ complexes through CH⋯O interactions (2.24-2.56 ).
