摘要

CuBrSe₃ has been synthesized by the reaction between CuBr₂ and Se in ethylene glycol (EG) solvent at 100 °C. In the process, CuBr₂ was reduced to brom-complexes of Cu(I), such as , the complexes participated in the reaction as intermediates. Based on experimental results and the structure characterization of CuBrSe₃ crystal, a possible mechanism for CuBrSe₃ formation was proposed. The mechanism suggests that Se chains assembly with the brom-complexes of Cu(I) to form CuBr helical chains, and then CuBrSe₃ crystal.
