Solvothermal reactions of 3,5‐dimethylpyrazole (Me 2 pz), and CuX in MeOH afforded two trinuclear complexes [Cu( X Me 2 pz)] 3 [ X = I ( 1 ); Br ( 2 )], where the halogenated ligand XMe 2 pz in 1 and 2 were in‐situ formed from the reaction of Me 2 pz with X – . The crystal structure of 1 was determined by X‐ray crystallography. It turned out that it has a classic [Cu 3 N 6 ] unit. The luminescence properties of 1 and 2 were investigated and the results show that both complexes have high photoluminescence quantum yields of 62 % and 84 % and long lifetimes of 21.7 μs and 30.5 μs, respectively.
