Control of magnetic performances of molecular magnets is essential but few efforts have been documented. A green and efficient sonication assisted synthesis of a new heterometallic diruthenium(ii,iii) carbonate, Na[Ni(H2O)4Ru2(CO3)4]·3H2O (1), was carried out by self-assembling in aqueous solution. Compound 1 exhibits spin-glass behavior below ∼5.0 K, and a systematic investigation of the ultrasonic irradiation influence on the powder samples reveals that their coercivity increases from 50 Oe to 743 Oe with the control of ultrasonic power under appropriate conditions.

通过超声辅助合成多金属碳自旋玻璃Na [Ni（H2O）4Ru2（CO3）4]·3H2O来提高磁硬度。

分子磁体的磁性能控制是必不可少的，但是很少有文献记载。通过在水溶液中自组装进行了绿色高效的超声辅助合成，合成了新的杂金属碳酸二钌（ii，iii）Na [Ni（H2O）4Ru2（CO3）4]·3H2O（1）。化合物1在低于〜5.0 K的条件下显示出自旋玻璃行为，对粉末样品的超声辐照影响进行系统研究表明，在适当的条件下，通过控制超声功率，其矫顽力从50 Oe提高至743 Oe。
