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 = (3) Å] interactions are observed between the BODIPY core and the tetramethylene substituents of neighbouring dimer pairs.

Comment Lipid droplets are metabolically active organelles (Beller et al., 2010; Bickel et al., 2009), which function as intracellular storehouses of lipid esters found inside almost all cells. LD540 is one of the dyes that can be used for multicolor fluorescence imaging for lipid droplets in both fixed and living cells (Spandl et al., 2009). In the structure of the title compound, the BODIPY core is planar having the average dihedral angle formed between the two pyrrole rings of 2.3 (3) (Fig. 1). The two tetramethylene substituents on either side of the BODIPY core at the 2,3- and 5,6-positions are in a half-chair conformation. Intermolecular F H C interactions (distance of (3) Å) between the fluoride (F3) and methyl (C23) groups of the opposite facing molecules connect the two LD540 molecules to form a dimer (Fig.2, Table 2). In a similar manner, the second fluoride (F2) atom forms an intermolecular F H C interaction (distance of (3) Å) to one of the CH 2 (C8) groups of the tetramethylene unit connecting the neighbouring dimer pairs in an infinite array through the crystal lattice (Fig. 3, Table 2). In addition to the F H C interactions, intermolecular C H π interactions [C18A H18A Cg1 i = Å and C17 H17A Cg2 ii = Å; Cg1 and Cg2 are the centroids of rings N4,C5,C10- C12 and N22,C21,C14-C16, respectively; symmetry codes: (i) x + 1, y, z; (ii) -x, -y + 1, -z + 1] and π π interactions [Cg2 Cg2 iii = (3) Å; symmetry code: (iii) -x + 1, -y + 1, -z +1] are observed between the BODIPY core and the tetramethylene substituents of the neighbouring dimer pairs. S2. Experimental The title compound was synthesized by a known method described by Christoph Thiele and co-workers (Spandl et al., 2009) using tetrahydropyrrole, acetylchloride and BF 3 -etherate as the starting material. For single-crystal X-ray analysis the crude product was recrystallized from dichloromethane yielding greenish red prism crystals. S3. Refinement All H atoms were visible in the electron density maps, but those bonded to C were ideally positioned and allowed to ride on their parent atoms with U iso (H) of 1.2 (or 1.5 for methyl) times U eq (C). One of the tetramethylene substituent is disordered over two positions (C18 C19) having fixed site occupation factors of 0.5. sup-1

All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
