The reaction of dimethylthallium(III) acetate and isatin-3-thiosemicarbazone (HisaTSC) afforded [TlMe 2(isaTSC)], which recrystallised from DMSO as [TlMe 2(isaTSC)(DMSO)]. In this crystal the Tl atom is bound to the S, N(3) and O atoms of an N(2)-deprotonated thiosemicarbazone ligand, to the O of a DMSO molecule, and to the two methyl C atoms. An additional Tl⋯O isaTSC interaction with a neighbouring molecule gives rise to a weakly bonded dimer in which the thallium atoms have distorted pentagonal bipyramidal environments. The changes induced in the solid-state IR spectrum of the free ligand by deprotonation and coordination are analysed and the 1H, 13C and 15N NMR spectra are also discussed.
