4,4'-Dimethyl-2,2'-bipyridine 1,1'-Dioxide

There are four molecules in a unit cell of the title compound, C₁₂H₁₂O₂N₂; the structure of only half a molecule has been determined because of its twofold rotational symmetry. The dihedral angle between the two pyridine rings is 61.3° and the non-bonded distance between O atoms in the N-oxide groups is 2.96 Å. The skew conformation of the skeleton is almost the same as that of the tetrakis(2,2'-bipyridine 1,1'-dioxide)lanthanum(III) complex.
