A reaction of [Cu(MeCN)4]BF4 with PzH (3,5-dimethylpyrazole) and BINAP [2,20-bis(diphenylphosphino)-1,10-binaphthyl] leads to the formation of mononuclear CuI complex [Cu(PzH)(BINAP)]BF4 containing the molecule of nondeprotonated pyrazole and one BINAP ligand with two phosphorus atoms chelating the metal. This complex exhibits a bright phosphorescence originating from the 3(M+L)LCT state at room temperature. At 77 K, the emission is splitted into two components: 3(M+L)LCT and 3LC transitions. © 2019
