4,4'-{Diazenediylbis[(1,4-phenyl­ene)bis­(carbon­yloxy)]}bis­(2,2,6,6-tetra­methyl­piperidinyloxidan­yl): the first crystal structure determination from powder data of a nitroxide radical

The structure of a nitroxide radical determined from laboratory X-ray powder diffraction data is reported for the first time. The attractive forces between the mol­ecules in the crystal structure are mainly of dispersive nature.
