Bromobis(diethyldithiocarbamato)(4-methoxyphenyl)tellurium(IV)

The crystals of the Te^IV 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 [Te...Br 3.423 (1) Å, C-Te...Br 173.1 (1)°] so that the molecules are joined into centrosymmetric pairs by this weak secondary coordination.
