Compound [Cr7S8(SCN)4(NH3)14](SH) and preparation method thereof

Abstract

The invention provides a compound [Cr7S8(SCN)4(NH3)14](SH) and a preparation method thereof, which comprise the following steps: uniformly mixing chromium chloride and thiourea, adding oxalic acid, sealing the reaction kettle, and heating the reaction kettle to react, and obtaining a black rod-shaped crystal, namely the compound [Cr7S8 (SCN) 4 (NH3) 11. According to the invention, [Cr7S8(SCN)4(NH3)14](SH) is synthesized by a simple solvothermal method for the first time, which has a stable rod-shaped single crystal structure, and can be used as a raw material to synthesize other chromium-containing sulfides through a simple thermal decomposition reaction, and has application value as a chemical reagent. The method is simple and easy to operate, does not need to be carried out under harsh vacuum reaction conditions, and has the advantages of cheap and easily available raw materials, low cost, low energy consumption and easy industrial production.
