Synthesis, crystal structure and electroluminescent properties of fac-bromotricarbonyl ([1,2,5]oxadiazolo[3',4':5,6]pyrazino- [2,3-f][1,10]phenanthroline) rhenium (I)

An efficient and simple synthetic protocol has been developed for preparation of [1,2,5] chacogenadiazolo[3', 4': 5,6] pyrazino[2,3-f][1,10] phenanthrolines. The first Re(I) bromotricarbonyl complex bearing [1,2,5] oxadiazolo[3', 4': 5,6] pyrazino[2,3-f][1,10] phenanthroline as a ligand was synthesized. Crystal structure of complex and free ligand, photo-and electroluminescent properties of fac-bromotricarbonyl ([1,2,5] oxadiazolo[3', 4': 5,6] pyrazino[2,3-f][1,10] phenanthroline) rhenium (I) were investigated.
