The title compound, C 34 H 16 N 4 O 4 , is a perylene±imide pigment utilized for H 2 gas sensors. There are two independent halfmolecules in the asymmetric unit. The symmetry of both molecules is C i . The angles between the each of the pyridyl rings and the perylene-imide skeleton are 77.7 (1) and
