The TeIV complexes p-MeOC6H4Te(Et2NCS2)2I (1) and p-MeOC6H4Te(Et2NCS2)2Br0.41I0.59 (3) have been synthesized by reacting p-MeOC6H4Te(Et2NCS2)3 with the elementary halogens. The crystals of (1) and (3) are isomorphous with the I atom position in (3) partially replaced by a Br atom. The structures are pentagonal bipyramidal with four S atoms [Te—S 2.624 (1)–2.733 (1) Å] and the halogen atom [Te—I 3.169 and 3.164 (1), Te—Br 2.904 (3) Å] in equatorial positions. The p-methoxyphenyl group is axial [Te—C 2.211 (3) and 2.151 (4) Å] and the second axial position is occupied by a halogen atom of a neighbouring molecule [Te...I 3.569 (1) and 3.558 (4), Te...Br 3.476 (9) Å, bond angles C—Te...I 176.7 (1) and 174.9 (4), C—Te...Br 176.3 (2)°] so that the molecules are joined into centrosymmetric pairs by this secondary coordination.
