1,1-Di­fluoro-3-phenyl-9-(pyridin-2-yl)-1H-1λ4,11λ4-1,3,5,2-oxadi­aza­borinino3,4-a1,8naphthyridine

摘要

In the title compound, C20H13BF2N4O, the central fused three-ring oxadi­aza­borininona­phthyridine system is planar (r.m.s. deviation of 0.03 Å). The phenyl ring lies in the plane of this ring system, making a dihedral angle of 0.61 (14)°, and is inclined to the pyridine ring by 9.02 (19)°. In the crystal, mol­ecules are connected by C—H⋯F hydrogen bonds, forming chains propagating along the b-axis direction. The chains are linked by offset π–π inter­actions inter­centroid distance = 3.4550 (13) Å, forming a three-dimensional supra­molecular architecture.
