In the title compound, C6H18N22+·2C9H3Br4O4·2CH4O, the carboxyl­ate and meth­oxy­carbonyl groups in one of the anions form dihedral angles of 71.9 (3) and 60.7 (3)°, respectively, with the aromatic ring while in the other anion these angles are 68.4 (3) and 56.8 (3)°, respectively. In the crystal, the constituent units are linked into a two-dimensional network parallel to the ab plane by N—H⋯O and O—H⋯O hydrogen bonds.

Comment top

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. In this paper, the structure of the title compound, (I), is reported.

The asymmetric unit of (I) contains one hexane-1,6-diaminium cation, two 3,4,5,6-tetrabromo-2-(methoxycarbonyl)benzoate anions and two methanol solvent molecules (Fig. 1). The dihedral angles formed by the aromatic ring and the mean planes of the carboxylate and methoxycarbonyl groups are 71.9 (3)° and 60.7 (3)°, respectively, in one of the anions [with Br1], and 68.4 (3)° and 56.8 (3)°, respectively, in the other anion [with Br5]. The bond lengths and angles are in agreement with those observed for ethylammonium 2-(methoxycarbonyl)-3,4,5,6-tetrabromobenzoate methanol solvate (Li, 2011a), 2-methylanilinium 3,4,5,6-tetrabromo-2-(methoxycarbonyl)benzoate methanol monosolvate (Li, 2011b) and propan-1-aminium 3,4,5,6-tetrabromo-2-(methoxycarbonyl)benzoate N,N-dimethylformamide monosolvate (Li, 2011c). The crystal structure is stabilized by N—H···O and O—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 30 min. Then hexane-1,6-diamine (0.58 g, 0.005 mol) was added to the above solution and mixed for 30 min at room temperature. After filtration, the solution was kept at room temperature for 5 d. Natural evaporation gave colourless single crystals of the title compound, suitable for X-ray analysis.

Refinement top

H atoms were initially located in a difference map and then refined in 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) and 1.5Ueq(O, N, methyl 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.
