摘要
The progress of the study on the magnetic properties of heteropolyoxometalates during the late decade is reviewed. Some anions of heteropolyoxometalates containing magnetic atoms, such as [M<sub>4</sub>（H<sub>2</sub>O）<sub>4</sub>(PW<sub>9</sub>O<sub>34</sub><sub>2</sub>]<sup>10-</sup> and [M<sub>4</sub>（H<sub>2</sub>O）<sub>4</sub>(P<sub>2</sub>W<sub>15</sub>O<sub>56</sub><sub>2</sub>]<sup>16-</sup>[M= Co（ Ⅱ ）, Zn（ Ⅱ ）, Cu（ Ⅱ ）, Mn（ Ⅱ ）,Ni（ Ⅱ ）], and [GaW<sub>9</sub>O<sub>37</sub>M<sub>3</sub>（H<sub>2</sub>O）<sub>3</sub>]<sup>n-</sup>[M= Fe（ Ⅲ ）, Cu（ Ⅱ ）, Co（ Ⅱ ）], showed ferromagnetic and antiferromagnetic properties. The combination of heteropoly anions and organic π-donor of TTF<sup>+</sup> （tetrathiofulvalene cation） results in a variety of magnetic properties. Furthermore, there is an interaction between the inorganic and organic components. The electrocrystallization technique can prepare the organic-inorganic salts of this kind, which will become the new member of molecular magnetic materials.Heteropoly blue is a kind of the mixed-valence complexes and its reduction electrons can be delocalized over anionic framework.

The progress of the study on the magnetic properties of heteropolyoxometalates during the late decade is reviewed. Some anions of heteropolyoxometalates containing magnetic atoms, such as [M4(H2O)4(PW9O34)2 10? and [M4(H2O)4(P2W15O56)2 16? [M = Co(II), Zn(II), CU(II), Mn(II), Ni(II)], and [GaW9O37M3 (H2O)3]n? [M = Fe(III), CU(II), CO(II)], showed ferromagnetic and antiferrmagnetic properties. The combination of heteropoly anions and organic π-donor of TTF+ (tetrathiofulvalene cation) results in a variety of magnetic properties. Furthermore, there is an interaction between the inorganic and organic components. The electrocrystallization technique can prepare the organic-inorganic salts of this kind, which will become the new member of molecular magnetic materials. Heteropoly blue is a kind of the mixed-valence complexes and its reduction electrons can be delocalized over anionic framework. The further study on the magnetic properties of heteropolyoxometalates will provide important information for the design of molecular materials.
