Özet

The title compound, C29H20N4O, is a derivative of 2H-pyrazolo[3,4-d] pyridazine and is non-planar, although consisting of planar fragments. The structure consists of planar fragments. There are two independent molecules in the asymmetric unit. The dihedral angle between the fused pyridazine and pyrazole rings is 2.61 (11)degrees in molecule A [3.19 (11)degrees in molecule B]. The crystal structure is stabilized by intramolecular and intermolecular C - H ... O interactions.
