Abstract

The dipyrrolopyrrole 2,6-bis(p-tolylimino)-4,7-dihydro-1,4,7-tri-p-tolyl-1H-dipyrrolo[3,2-b:2′, 3′-d]pyrrole (1) was obtained from the reaction of a 1,4-diaza-1,3-diene, glyoxal bis(p-tolylimine), in the presence of FeCl2. Crystals of 1, C43H32N5, are triclinic, space group, P1, with a = 10.014(3) Å, b = 13.212(3) Å, c = 13.710(3) Å, α = 106.31(2)°, β = 95.79(2)°, γ = 105.77(2)°, V = 1644 Å3 , Z = 2, Dcalcd = 1.211 g cm-1, R = 0.026, and Rw = 0.057. The compound is thought to result from a series of metal-mediated condensations of the 1,4-diaza-1,3-diene precursor.
