First examples of hybrids based on polyoxometalates, metal halide clusters and organic ligands

Abstract Two new organic–inorganic compounds based on polyoxometalates, metal halide clusters and organic ligands: [BW 12 O 40 ] 2 [Cu 2 (Phen) 4 Cl](H 2 4, 4′-bpy) 4 ·H 3 O·5H 2 O ( 1 ) and [HPW 12 O 40 ][Cd 2 (Phen) 4 Cl 2 ](4, 4′-bpy) ( 2 ) (Phen=1, 10-phenanthroline, bpy=bipyridine), have been prepared and characterized by IR, UV–vis, XPS, XRD and single crystal X-ray diffraction analyses. Crystal structure analyses reveal that compound 1 is constructed from [BW 12 O 40 ] 5− , metal halide clusters [Cu 2 (Phen) 4 Cl] + and 4, 4′-bpy ligands, while compound 2 is constructed from [PW 12 O 40 ] 3− , metal halide cluster [Cd 2 (Phen) 4 Cl 2 ] 2+ and 4, 4′-bpy ligands. Compound 1 and compound 2 are not common hybrids based on polyoxometalates and metal halide clusters, they also contain dissociated organic ligands, therefore, compound 1 and 2 are the first examples of hybrids based on polyoxometalates, metal halide clusters and organic ligands.
