Abstract: In the title compound, [TeBr4(C22H23OP)]·CH3CN, 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 interaction helps to establish the conformation. In the crystal, there is a weak secondary bonding interaction [Te...N = 3.456 (11) Å] between the Te atom and the N atom of the solvent molecule, which completes a distorted TeNCBr4 octahedron. Inversion dimers linked by pairs of C-H...Br interactions are also observed.
