Dimethyl(2,6-diacetyl-pyridine-monothiosemicarbazonato)thallium(III), [TlMe2(L)], and Diphenyl-(2,6-diacetyl-pyridine-monothiosemicarbazonato)thallium(III) chloroform solvate, [TlPh2(L)],CHCl3 were prepared by reacting the corresponding diorganothallium(III) hydroxide with 2,6-diacetyl-pyridinemonothiosemicarbazone (HL). [TlMe2(L)] crystallizes in the triclinic space group (no. 2) with . [TlPh2(L)]
