In an effort to discover new potential boron-dipyrromethene (BODIPY) dyes, the title compound, C19H17BF2N4O4, was prepared from 2,4-dimethyl-pyrrole, 3,5-dinitro-benzaldehyde and boron trifluoride in a one-pot reaction. The BODIPY fragment is nearly planar, with a maximum deviation from the least-squares plane of 0.251 (2) Å, and the benzene ring is inclined at a dihedral angle of 86.8 (6)° to the BODIPY mean plane. In the crystal, pairs of C-H⋯F hydrogen bonds connect neighbouring mol-ecules into inversion dimers, which are linked by further strong C-H⋯F inter-actions, forming a supra-molecular layered array parallel to the bc plane.
