    Notes: The powder data for 1,3,5-trichlorobenzene (1,3,5-TCB) and 1,3,5-tribromobenze (1,3,5-TBB) at 293 K are reported. These compounds are isomorphous, orthorhombic, P212121, Z = 4 with a = 13.971 (3), b = 13.251 (2), c = 3.921 (1) Å, V = 725.9 (4) Å3, Dx = 1.660 Mg m−3 for 1,3,5-TCB and a = 14.244 (3), b = 13.577 (2), c = 4.084 (1) Å, V = 789.8 (5) Å3, Dx = 2.648 Mg m−3 for 1,3,5-TBB. These values are more accurate than those previously reported [Milledge & Pant (1960). Acta Cryst. 13, 285–290]. The JCPDS Diffraction File Nos. are 34-1989 for 1,3,5-TCB and 34-1988 for 1,3,5-TBB.

    Notes: The title compound C7H6Br2 (also called 3,5-dibromotoluene) is orthorhombic, space group P212121 with a = 14.426(2), b = 13.636(2), c = 4.076(1) Å, V = 801.8(3) Å3, Z = 4, Dx = 2.071 Mg m−3. The space group and preliminary cell parameters have been determined by single-crystal diffraction methods (Bragg, Weissenberg and precession patterns). The cell dimensions have been refined by least squares from accurate powder diffractometer data recorded at T = 293(1) K (quartz as internal standard, Cu Kα1−Kα2 correction so that λ = 1.54056 Å). The indexed powder data are given. No phase transition is detected between 123 K and the melting point 311.1(2) K (differential scanning calorimetry and Guinier–Lenné analysis). The results show that 1,3-dibromo-5-methylbenzene is isomorphous with 1,3,5-trichlorobenzene and 1,3,5-tribromobenzene. The JCPDS Diffraction File No. For C7H6Br2 is 36-1991.
