摘　　要：通过水热方法合成了一种混合钼钒多金属氧酸盐[Cu(phen)2]4{HPMo8ⅥV6ⅣO42[Cu(phen)]2}.2H2O.采用X射线单晶衍射、元素分析、红外光谱对其进行了表征,同时对其磁学性质进行了研究.结果表明:标题化合物包含高度还原的二帽假Keggin结构的多氧阴离子支撑2个过渡金属配合物,即铜配合物阳离子[Cu(phen)2]+和结晶水;该化合物呈铁磁性相互作用.A mixed molybdenum vanadate polyoxometalate [Cu（phen）2]2{HPMO8^Ⅵ7V6ⅣO42[Cu（phen）]2}·2H2O have been synthesis though hydrothermal method, The title compound characterized by single crystal X ray diffraction analysis, elemental analysis and IR spectra. Compound consists of highly reduced hi-capped pseudo Keggin polyoxoanion supporting two transition complexes, copper complexes cation [Cu（phen）2] ＋ and lattice water. The magnetism properties of title compound have been studied. The study of magnetic indicate that this compound exhibits antiferromagnetic coupling interaetions.
