Abstract
- Abstract: Two novel compounds, (H2bpy)0.5{[Ni(H2O)5][Ni(Hbpy)(H2O)4][Mo5P2O23]} 1 and (H2bpy)0.5{[Co(H2O)5][Co(Hbpy)(H2O)4][Mo5P2O23]} 2, have been prepared under mild hydrothermal conditions and structurally characterized by single-crystal X-ray diffraction. The two compounds are isostructural and crystallize in the triclinic space group with a=10.760(2)Å, b=10.771(2)Å, c=17.566(4)Å, α=98.56(3)°, β=96.66(3)°, γ=111.10(3)°, and Z=2 for the compound 1, and a=10.770(2)Å, b=10.815(2)Å, c =17.684(4)Å, α=98.96(3)°, β=96.41(3)°, γ=111.37(3)°, and Z=2 for the compound 2. Crystal structure analysis reveals that 1 and 2 are not only the first examples of polyoxometalate supported transition metal complexes constructed by diphosphopentamolybdate cluster and transition metal complex fragments but also the first examples of disupporting polyoxometalate compounds where two distinct transition metal complex fragments are supported on the polyoxoanion cluster.
