A new compound formulated（ C10H22N2）3[Cu9I14Br]（ C10H22N2= N,N’-diethyl-1,4-diazabicyclo-[2. 2. 2]octane） was synthesized under solvothermal condition via in situ copper reduction and characterized by single crystal X-ray diffraction（ XRD）,elemental analysis,powder X-ray diffraction（ PXRD） and Infrared spectroscopy.（ C10H22N2）3[Cu9I14Br] crystallizes in monoclinic crystal system,space group C2/c with a = 2. 6233（ 5） nm,b = 1. 6299（ 3） nm,c = 1. 6707（ 3） nm,β = 117. 31（ 3） °,V = 6. 347（ 2） nm3. The title compound is constructed by organic cationic templates and anionic copper（ Ⅰ） halide chains. The organic templates in this structure originated from the in situ N-alkylation reaction between N,N’-dimethyl-1,4-diazabicyclo[2. 2. 2]octane and alcohol solution. At ambient temperature,the title compound showed excellent luminescent property.
