In the title compound, (C24H20As)TcO(C9H11N3O5S).CHCl3, technetium is coordinated to three amide N atoms and one S atom which form a square pyramid, with the oxo group occupying the apical position such that the Tc atom lies 0.771 (5) Å above the least-squares basal plane. The methyl group adopts a syn configuration with respect to the oxo-metal group. The chloroform solvate molecule exhibits site occupation disorder with three positions for the Cl atoms.
