here The fused five- and three six-membered rings of the anthra[1,2-d]imidazoletrione part of the title compound, C27H20N4O4, show two different substituents at the imidazole N atoms, viz.an allyl group and a [3-(pyridin-4-yl)-4,5-dihydroisoxazol-5-yl]methyl group.The fused-ring system is approximately planar [r.m.s.

deviation = 0.232 (2) Å], but is slightly buckled along the common edge of the two pairs of adjacent rings, with a dihedral angle between them of 11.17 (6)°.The isoxazole ring makes dihedral citronella horse shampoo angles of 27.2 (2) and 12.

7 (2)° with the imidazole and pyridine rings, respectively.Weak C—H.O and C—H.N hydrogen bonds ensure the cohesion of the crystal structure, forming a three-dimensional network.
