The powder data for p ‐bromochlorobenzene/ p ‐dibromobenzene mixed crystals [ p BCB] x [ p DBB] 1 − x at 293 K are reported; their thermal stability at 293 K is given. Vertical diffractometer, graphite monochromator, Cu K α, λ = 1.54056 Å. They are all isomorphous, monoclinic, P 2 1 / a with Z = 2. a = 15.176(6), b = 5.847(3), c = 4.078(2) Å, β = 112.57(3)°, V = 334.2 Å 3 , D x = 1.947 Mg m −3 for [ p BCB] 0.90 [ p DBB] 0.10 ; JCPDS No. 36‐1975. a = 15.222 (7), b = 5.847 (3), c = 4.083(2) Å, β = 112.60(3)°, V = 335.5 Å 3 , D x = 1.984 Mg m −3 for [ p BCB] 0.80 [ p DBB] 0.20 ; JCPDS No. 36‐1974. a = 15.260(5), b = 5.839(2), c = 4.084(2) Å, β = 112.57(1)°, V = 336.1 Å 3 , D x = 2.024 Mg m −3 for [ p BCB] 0.70 [ p DBB] 0.30 ; JCPDS No. 36‐1973. a = 15.298(4), b = 5.845(3), c = 4.091(2) Å, β = 112.60(2), V = 337.7 Å 3 , D x = 2.058 Mg m −3 for [ p BCB] 0.60 [ p DBB] 0.40 ; JCPDS No. 36‐1972. a = 15.340(4), b = 5.844(2), c = 4.092(2) Å, β = 112.60(2)°, V = 338.7 Å 3 , D x = 2.096 Mg m −3 for [ p BCB] 0.50 [ p DBB] 0.50 ; JCPDS No. 36‐1971. a = 15.370(5), b = 5.843(2), c = 4.097(2) Å, β = 112.62(2)°, V = 339.6 Å 3 , D x = 2.134 Mg m −3 for [ p BCB] 0.40 [ p DBB] 0.60 ; JCPDS No. 36‐1970. a = 15.404(6), b = 5.840(2), c = 4.100(2) Å, β = 112.67(2)°, V = 340.4 Å 3 , D x = 2.172 Mg m −3 for [ p BCB] 0.30 [ p DBB] 0.70 ; JCPDS No. 36‐1969. a = 15.437(5), b = 5.842(2), c = 4.103(2) Å, β = 112.66(2)°, V = 341.4 Å 3 , D x = 2.209 Mg m −3 for [ p BCB] 0.20 [ p DBB] 0.80 ; JCPDS No. 36‐1968. a = 15.468(4), b = 5.838(2), c = 4.104(2) Å, β = 112.70(2)°, V = 341.9 Å 3 , D x = 2.249 Mg m −3 for [ p BCB] 0.10 [ p DBB] 0.90 ; JCPDS No. 36‐1967.
