Abstract:
In the title compound, [TeBr(4)(C(22)H(23)OP)]·CH(3)CN, the Te atom exhibits a square-pyramidal coordination with an apical Te-C bond and four basal Te-Br bonds. The conformation of the aliphatic C-C-C-C chain is gauche [torsion angle = -67.7 (8)°]. A weak C-H⋯Br inter-action helps to establish the conformation. In the crystal, there is a weak secondary bonding inter-action [Te⋯N = 3.456 (11) Å] between the Te atom and the N atom of the solvent mol-ecule, which completes a distorted TeNCBr(4) octa-hedron. Inversion dimers linked by pairs of C-H⋯Br inter-actions are also observed.

Consider the bromination of cyclopentene. Molecular bromine is polarized in the proximity of the π electrons of cyclopentene. An electrophilic bromine atom adds across the double bond, forming a cyclic bromonium ion intermediate.
