Abstract: The title compound, C18H21BF2N2, is a lipophilic dye based on a BODIPY fluorophore backbone, which was developed for microscopic imaging of lipid droplets; the molecule has a planar BODIPY core [dihedral angle between the pyrrole rings = 2.3 (3)°] and two tetramethylene substituents at the 2,3- and 5,6-positions in a half-chair conformation. One of the tetramethylene substituents is disordered over two two sets of sites with site occupancies of 0.5. In the crystal, pairs of C-HF interactions link the molecules into inversion dimers. Neighbouring dimers are linked by further C-HF interactions, forming an infinite array. C-H and - [centroid-centroid distance = 4.360 (3) Å] interactions are observed between the BODIPY core and the tetramethylene substituents of neighbouring dimer pairs.
