Paragraph 0037;0039-0040, (2018/10/11)
Belonging to the technical field of functional materials, the invention discloses a preparation method of an allomorph variant of [1-(4'-cyanobenzyl)pyridine][bis(maleonitriledithiolato)nickel (III)].The method utilizes I2 to oxidize [1-(4'-cyanobenzyl)pyridine]2[bis(maleonitriledithiolato)nickel (II)] to obtain [1-(4'-cyanobenzyl)pyridine][bis(maleonitriledithiolato)nickel (III)], then performing filtering at the end of the oxidation reaction, washing the filter cake N times, then dissolving the washed filter cake in acetonitrile, performing filtering, and volatilizing the filtrate for crystallization, thus obtaining the allomorph variant of bis(maleonitriledithiolato)nickel (III). The preparation method provided by the invention is simple and feasible, and the obtained product has highyield and high purity, and is suitable for industrial application.
