以亲核的三价砷/锑/铋为杂原子多钨氧酸盐构筑块作为前驱体，把亲电的过渡金属[特别是锰(III)、铁(II/III)、钴(II)、镍(II)]和稀土金属[特别是铽(III)、镝(III)]离子同时引入反应体系，系统探索它们之间的反应配条件，制备新型以三价砷/锑/铋为杂原子多钨氧酸盐过渡-稀土异金属磁性材料，对其组成、结构和磁性等进行深入研究。为了得到有应用价值的单分子磁性材料，把具有单离子各向异性的过渡金属离子和单电子数多、具有强旋轨耦合作用的稀土金属离子引入了反应体系，并选用具有电子传递功能的有机配体来调控过渡金属和稀土金属之间的电子传递交换作用。通过大量实验探索，发现三价砷/锑/铋多钨氧酸盐构筑块、过渡金属、稀土金属之间的协同配位规律,通过实验测试和理论计算，对目标材料的磁学性质进行分析，探究材料单分子磁性产生机理，因此，该项研究既具有重大的理论研究意义又具有潜在的应用价值。

Nucleophilic trivalent As/Sb/Bi containing polyoxotungstate precursors,electrophilic transition-metal [especially for Mn(III), Fe(II/III), Co(II),Ni(II)] and rare-earth [especially for Tb(III), Dy(III)] cations will be simultaneously introduced to the same reaction system to prepare novel trivalent As/Sb/Bi containing polyoxotungstate transition-metal-rare-earth heterometallic magnetic materials on the base of systematically exploring their appropriate reaction conditions. Their compositions, structures and magnetic properties of the desired materials are deeply investigated. In oder to obtain single-molecule magnetic materials with potential applications, single-ion anisotropic transition- metal cations and rare earth cations with many single electrons and strong spin-orbital coupling interactions will be introduced to the reaction system. Moreover, use the functional organic lignads with electronic delocalization characteristics to tune the electron transfer and magnetic exchange behavior between transition-metal cations and rare-earth cations. Through a large number of experiments,discover the collaborative coordination rules between trivalent AS/Sb/Bi containing polyoxotungstate precursors, transition-metal cations and rare-earth cations. The magnetic properties of desired materials will be analyzed through experimental magnetic measurements and theoretical calculations. The generation mechanism of these single molecular magnetic materials will be also probed. Therefore, this work not only has great theoretical significance, but also has potential application value.
