The crystal structures of CuTe2Br and CuTe2I have been refined on the basis of single crystal data. Both compounds crystallize monoclinically in space group P21/c. The structures are isotypic with that of CuTe2Cl. The lattice parameters of CuTe2Br are a = 834.5(8) pm, b = 492.8(4) pm, c = 1573.3(5) pm and β = 135.3(2)°. The unit cell dimensions of CuTe2I are a = 866.5(8) pm, b = 491.4(4) pm, c = 1649.6(3) pm and β = 135.1(2)°.
