The invention discloses a cobalt oxygen cluster compound constructed by antimony tartrate and a preparation method thereof. A molecular formula is as follows: {Na4[Co2Sb12(mu 3-O)6(mu 3-OH)2(mu 4-O)3(tartrate)6].19.5H2O}2, wherein tartrate is meso-D/L tartaric acid. The cobalt oxygen cluster compound constructed by the antimony tartrate is prepared by taking meso-antimony potassium tartrate as a ligand and cobalt acetate as a metal salt, and adding the two into an appropriate concentration of acetic acid/sodium acetate buffer solution. The preparation method has the advantages of simple method, energy saving and environmental protection, high yield, easy availability of raw materials and low price; a dipolymer metal oxygen cluster compound structure comprises a dinuclear cobalt metal unit, dinuclear cobalt ions performs weak ferromagnetic interaction, and or intermolecular interaction, and thus being capable of taking as a molecular magnetic material.
