The powder data for p ‐bromochlorobenzene(pBCB) and p ‐dichlorobenzene/ p ‐bromochlorobenzene mixed crystals [pDCB] x [pBCB] 1 − x at 293 K are reported; their thermal stability at 293 K is given. Vertical diffractomer, graphite monochromator, Cu K α, λ = 1.5405 Å. They are all isomorphous, monoclinic, P 2 1 / a with Z = 2. a = 15.134(4), b = 5.843(2), c = 4.073(1) Å, β = 112.53(1)°, V = 332.7 Å 3 , D x = 1.911 Mg m −3 for pBCB. a = 14.890(5), b = 5.848(5), c = 4.046(2) Å, β = 112.53(2)°, V = 325.4 Å 3 , D x = 1.636 Mg m −3 for [pDCB] 0.70 [pBCB] 0.30 . a = 15.004(6), b = 5.840(3), c = 4.059(2) Å, β = 112.48(2)°, V = 328.6 Å 3 , D x = 1.755 Mg m −3 for [pDCB] 0.40 [pBCB] 0.60 . a = 15.101(4), b = 5.844(2), c = 4.066(2) Å, β = 112.51(2)°, V = 331.5 Å 3 , D x = 1.873 Mg m −3 for [pDCB] 0. 10 [pBCB] 0.90 . The JCPDS Nos. are: 36‐1995 for pBCB; 36‐1994 for [pDCB] 0.70 [PBCB] 0.30 ; 36‐1993 for [pDCB] 0.40 [pBCB] 0.60 ; 36‐1992 for [pDCB] 0.10 [pBCB] 0.90 . Data for [pDCB] 0.90 [pBCB] 0.10 , [pDCB] 0.80 [pBCB] 0.20 , [pDCB] 0.60 [pBCB] 0.40 , [pDCB] 0.50 [pBCB] 0.50 , [pDCB] 0.30 [pBCB] 0.70 and [pDCB] 0.20 [pBCB] 0.80 have also been measured and are available from the authors or as part of the Supplementary Publication.
