Abstract

The invention discloses an organic-inorganic hybridization molecular magnet with room-temperature metallicity and a preparation method of the molecular magnet. The molecular formula of the molecular magnet with the room-temperature metallicity is BETS3[Cu2(C2O4)3]B2, wherein BETS represents disulfo-diethylene tetraselenafulvalene; and B represents an alcohol compound. The preparation method of the molecular magnet with the metallicity comprises the step of performing electrochemical reaction on an ammonium salt of cupric oxalate with BETS in an electrochemical tank by taking the alcohol compound as an electrolyte solution so as to obtain the molecular magnet with the room-temperature metallicity on an anode. According to the preparation method of the molecular magnet with the room-temperature metallicity, single crystal of the molecular magnet with room-temperature metallicity is prepared in an organic solvent system from an organic pi electron system and Jahn-Teller distorted magnetic anion. The molecular magnet with room-temperature metallicity, which is provided by the invention, is good in crystal quality, single in product and high in yield.

Description

[0001] This application is a divisional application with the application number 201210209161.2, the filing date is June 20, 2012, and the invention name is "organic-inorganic hybrid room temperature metallic molecular magnet and its preparation method". technical field [0002] The invention relates to an organic-inorganic hybrid room-temperature metallic molecular magnet and a preparation method thereof. Background technique [0003] Molecular-based materials play a huge advantage in the preparation of new composite functional materials due to their light weight and molecular design. Room-temperature molecular magnets with electrical conductivity (semiconductor, metal), air stability, and long-range magnetic order at room temperature are pursued by international materials scientists, physicists, and chemists due to their broad application prospects in molecular spintronics. The goal. [0004] So far, there is only V(TCNE) reported by J.S.Miller in the world 2 (CH 2 Cl 2...
