3,6-Di-4-pyridylpyrrolo3,4-cpyrrole-1,4(2H,5H)-dione

摘要

The centrosymmetric title compound, C16H10N4O2, is an organic red pigment utilized for H-2 gas sensors. The centrosymmetric diketopyrrolopyrrole moieties are connected by bifurcated N...H...O hydrogen bonds to form a ribbon structure along [110] and [1(1) over bar 0] alternately. The molecules are stacked in a 'hunter's fence' ( viz. when viewed from the side, molecules, slipped by 45degrees within molecular stacks, cross each other in a fence-like structure) fashion along the a axis.
