8,19-Dimethyl-8,19-dihydro-8,19-ethanoanthra[2'',3'':2,3;6'',7'':2',3']di-1,4-dioxino[5,6-b;5',6'-b']diquinoxaline.

The title compound, C(34)H(22)N(4)O(4), results from the reaction of 2,3,6,7-tetrahydroxy-9,10-dimethyl-9,10-dihydro-9,10-ethanoanthracene with 2,3-dichloroquinoxaline. The molecule, which contains a binary crystallographic symmetry axis, comprises two planar 'wings' around a central bicyclic unit. The non-ideal geometry of the latter evidences some strain, as in previous compounds with the same central core. Each molecule is involved in pi-pi interactions with four of its neighbours, oriented upside-down, which results in the formation of sheets of tightly packed molecules.
