Abstract top

In an effort to discover novel and potential boron-dipyrromethene (BODIPY) dyes, the title compound, C19H18BF2N3O2, was prepared from 2,4-dimethylpyrrole, 4-nitrobenzaldehyde and BF3·Et2O in a one-pot reaction. There are two independent molecules, A and B, in the asymmetric unit in which the dihedral angles between the benzene ring and boron-dipyrromethene mean plane have significantly different values [82.71 (8)° for molecule A and 73.16 (8)° for molecule B]. Intermolecular C-H...[pi] interactions help to stabilize the crystal structure.

Comment top

In the past few years, many novel boron-dipyrromethene (BODIPY) dyes were developed for fluorescence analysis (Weiner et al., 2001; Gabe et al., 2004) and their crystal structures were investigated at the same time (Euler et al., 2002a,b). As part of our ongoing studies of the substituent effect on the solid-state structures of BODIPY derivatives (Cui et al., 2006), we report herein the crystal strcuture of the title compound, 4,4-difluoro- 1,3,5,7-tetramethyl-8-(4'-nitrophenyl)-4-bora-3a,4a-diaza-s-indacene, (I).

The asymmetric unit of the title compound is shown in Fig. 1. There are two independent unique molecules [lablled A and B], in which the dihedral angles between the benzene ring and boron-dipyrromethene mean plane have significantly different values [82.71 (8)° for molecule A, 73.16 (8)° for molecule B]. In the crystal structure, there also exist intermolecular weak edge-to-face C—H···π [C18-H18A···Cg1i (Cg1 = N4, C26, C28, C29, C31): H18A···Cg1, 2.93 Å, C18···Cg1, 3.784 (4) Å, i = x, y, z; and C35-H35A···Cg2ii (Cg2 = N5, C21-C23, C25): H35A···Cg2, 2.90 Å, C35···Cg2, 3.648 (5) Å, i = -x + 3/2, y + 1/2, -z + 1/2 ] interactions, which help to reinforce the packing lattice.

Experimental top

Compound (I) was prepared from 2,4-dimethylpyrrole and p-nitrobenzaldehyde in a one-pot reaction (Kollmannsberger et al., 1998). General procedure: 4.5 mmol of 2,4-dimethylpyrrole and 2 mmol of the aldehyde were dissolved in 150 ml of absolute dichloromethane under nitrogen atmosphere. One drop of trifluoroacetic acid was added and the solution was stirred at room temperature until TLC-control showed complete consumption of the aldehyde. At this point, 2 mmol dichlorodicyanobenzoquinone (DDQ) was added, and stirring was continued for 10 min followed by addition of 4 ml of triethylamine and 4 ml of boron trifluoride etherate quickly. After stirring for another 2 h, the reaction mixture was washed with water and dried, and the solvent was evaporated. The residue was chromatographed twice on a silica column (the mixture of dichloromethane and hexane as eluted solvent). Total yield: 48%. Orange crystals. 1H NMR (CDCl3): δ 1.36 (s, 6H, CH3), 2.57 (s, 6H, CH3), 6.02 (s, 2H, CH), 7.55 (d, 2H, CH, J = 21 Hz), 8.40 (d, 2H, CH, J = 22 Hz). MS (ESI), m/z: 368.2 [M—H]-. HRMS: [M—H]- calculated: 368.1496, measured: 368.1472.

Red single crystals suitable for X-ray analysis were obtained by dissolving (I) (0.2 g) in a hexane/dichloromethane (15 ml, v:v: 1:3) mixture and slowly evaporating the solvent at room temperature for a period of about two weeks.

Refinement top

All H atoms bound to C atoms were assigned to calculated positions, with C—H = 0.96 Å (methyl) and 0.93 Å (aromatic), and refined using a riding model, with Uiso(H)=1.2Ueq (C).

Special details top

Geometry. 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.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
