In the anion of the title solvated molecular salt, C3H10N+·C9H3Br4O4·C3H7NO, the dihedral angles formed by the aromatic ring and the mean planes of the carboxyl­ate and meth­oxy­carbonyl groups are 64.3 (3) and 75.2 (3)°, respectively. The C atoms of the propan-1-aminium cation are disordered over two sets of sites in a 0.65 (3):0.35 (3) ratio. The crystal structure is stabilized by N—H⋯O hydrogen bonds.

4,5,6,7-Tetrabromo-2-ethylisoindoline-1,3-dione is an important flame retardant. 3,4,5,6-Tetrabromo-2-(methoxycarbonyl)benzoic acid is an intermediate in the synthesis of this flame retardant. The asymmetric unit of the title compound contains one propan-1-aminium cation, one 3,4,5,6-tetrabromo-2-(methoxycarbonyl)benzoate anion and one N,N-dimethylformamide solvent molecule (Fig. 1). In the anion of the title compound, the dihedral angles formed by the benzene ring and the mean planes of the carboxylate and methoxycarbonyl groups are 64.3 (3) and 75.2 (3) °, respectively. The carbon atoms of the propan-1-aminium cation are disordered. The bond lengths and angles are in agreement with those which are related in ethylammonium 2-(methoxycarbonyl)-3,4,5,6-tetrabromobenzoate methanol solvate (Li, 2011a) and in 2-Methylanilinium 3,4,5,6-tetrabromo-2-(methoxycarbonyl)benzoate methanol monosolvate(Li, 2011b). The crystal structure is stabilized by N—H···O hydrogen bonds (see Fig. 2 and Table 1).

Experimental top

A mixture of 4,5,6,7-tetrabromoisobenzofuran-1,3-dione (4.64 g, 0.01 mol) and methanol (15 ml) was refluxed for 0.5 h. Then propan-1-amine (0.59 g, 0.01 mol) was added to the above solution and mixed for 30 min at room temperature. After filtration, filter cake was disolved in N,N-dimethylformamide (10 ml), the solution was kept at room temperature for 15 d. Natural evaporation gave colourless single crystals of the title compound, suitable for X-ray analysis.

Refinement top

H atoms were refined using a riding model with C—H = 0.96–0.97 Å, N—H = 0.89 Å, O—H = 0.82Å and Uiso(H) = 1.2Ueq(C) or 1.5Ueq(O, N, methyl C).

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.
