摘要
Two new compounds, [Ni（en）2]{[Ni（en）2]2[Mo^Ⅵ 6Mo^V2^Ⅳ8O40（SiO4）]}[（NH2）2（C2H4）2NH]·2H2O（1） and [Ni（en）2] { [Ni（en）2]2[Mo^Ⅵ5Mo^V3^Ⅳ8O40（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 ID chains are further assembled into a 3D supramolecular network with different packing modes via hydrogen bonds. The magnetic susceptibiltiy of compound 1 demonstrates the presence of antiferromagnetic interactions.
