Two members of the family dihalo(2,2′:6′,2′′‐terpyridyl)copper(II), Cu(terpy) X 2 X = Br − , I − , have been prepared by reaction in solution. They have space groups Ia and P 2 1 / a respectively. Powder patterns of Cu(terpy)Br 2 and Cu(terpy)I 2 have been indexed. Their cell constants are, for the bromide compound: a = 13.791(3), b = 9.291(2), c = 11.477(5) Å, β = 96.94(2)°, U = 1459.8(6) Å 3 , D m = 2.05 (4), D x = 2.07 Mg m −3 , Z = 4; and, for the iodide compound: a = 16.216(2), b = 8.804(1), c = 10.958(6) Å, β = 93.55(2)°, U = 1561.7(7) Å 3 , D m = 2.32(1), D x = 2.34 Mg m −3 , Z = 4. Crystal physics data are reported. Both follow the Curie–Weiss law and exhibit μ eff values of 1.93 BM (17.9 × 10 −24 A m 2 ) (307 K) and 1.75 BM (16.23 × 10 −24 A m 2 ) (309 K), respectively. The JCPDS Diffraction File Nos. are: Cu(C 15 H 11 N 3 )Br 2 33–1986; Cu(C 15 H 11 N 3 )I 2 33–1984.
