Abstract

The invention belongs to the technical field of preparation of novel chemical materials and particularly relates to a ferromagnetic organic-inorganic hybrid nine-nucleus manganese-substituted sandwich antimoniotungstate having a spin glass behavior. The chemical formula of the antimoniotungstate is [Na(H2O)6]<2>H<4>[Mn(H2O)3]<2>{Mn<7>(H2O)<8>(C2O4)<3>[B-alpha-SbW9O<33>]<2>}.27H2O. The compound is prepared by reacting MnCl<2>.4H2O, oxalic acid, and an antimoniotungstate precursor that is Na<9>[B-alpha-SbW9O<33>].19.5H2O in an aqueous solution, is a ferromagnetic material having the spin glass behavior, can be adopted as a novel magnetic recording material, and has a good application prospect in the field of magnetic materials. A preparing method is simple, easy to operate and low in cost.

Description
