3,6-Di-4-pyridylpyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione

J. Mizuguchi, T. Imoda and H. Takahashi

Abstract: The centrosymmetric title compound, C₁₆H₁₀N₄O₂, is an organic red pigment utilized for H₂ gas sensors. The centrosymmetric diketopyrrolopyrrole moieties are connected by bifurcated NHO hydrogen bonds to form a ribbon structure along [110] and [10] alternately. The molecules are stacked in a `hunter's fence' (viz. when viewed from the side, molecules, slipped by 45° within molecular stacks, cross each other in a fence-like structure) fashion along the a axis.
