The crystals of the TeIV complex p-CH3OC6H4Te(Et2NCS2)2Br are isomorphous with those of the the iodine and mixed iodine/bromine analogues previously investigated. The structure is pentagonal bipyramidal at the Te atom with four S atoms [Te-S 2.618-2.721 (1) Å] and the Br atom [Te-Br 2.943 (1) Å] in equatorial positions. The p-methoxyphenyl group is axial [Te-C 2.147 (3) Å]. The second axial position is approached by a Br atom of a centrosymmetrically related complex [TeBr 3.423 (1) Å, C-TeBr 173.1 (1)°] so that the molecules are joined into centrosymmetric pairs by this weak secondary coordination.
