| Abstract: | Two new compounds, [Ni(en)2]{[Ni(en)2]2[MoVI6MoV2VIV8O40(SiO4)]}[(NH2)2(C2H4)2NH]·2H2O(1) and [Ni(en)2]{[Ni(en)2]2[MoVI5MoV3VIV8O40(VO4)]}(en)·H2O(2)(en=ethylenediamine), have been hydrothermally synthesized and characterized by elemental analysis, infrared(IR), X-ray photoelectron spectroscopy(XPS), electron spin-resonance(ESR) and thermogravimetric(TG) analysis and single-crystal X-ray diffraction(XRD) analysis. Both the compounds exhibit a 1D chain composed of bi-supporting tetra-capped Keggin clusters and nickle coordination fragments. The 1D chains are further assembled into a 3D supramolecular network with different packing modes via hydrogen bonds. The magnetic susceptibility of compound 1 demonstrates the presence of antiferromagnetic interactions. |
