13b,13c-Di-2-pyridyl-5,7,12,13b,13c,14-hexa­hydro-6H,13H-5a,6a,12a,13a-tetra­azabenz[5,6]azuleno[2,1,8-ija]benz[f]azulene-6,13-dione methanol hemisolvate

The title compound, C(30)H(24)N(6)O(2)·0.5CH(3)OH, a glycoluril derivative with two pyridine substituents on the convex face of the glycoluril system, is an important inter­mediate for the synthesis of more complex glycoluril derivatives. The compound crystallizes with two independent mol­ecules in the asymmetric unit, one of which exhibits disorder of one benzene ring over two orientations with refined site occupancy factors 0.65 (4):0.35 (4). The crystal structure contains several short C—H⋯O contacts, and the methanol mol­ecule forms an O—H⋯O hydrogen bond to one of the glycoluril mol­ecules.
