Reaction of the PtCl2-6 ions with thiourea, N-methyl-, N,N'-dimethyl-, and N,N,N'-trimethylthiourea, respectively, led to complexes analogous to those formed on the reaction of the PtCl2-4 ion with these ligands. Formamidine disulfide or its alkyl derivatives were identified as the oxidation products. N,N,N',N'-Tetramethylthiourea and N,N'-ethylenethiourea afforded in the same conditions the Pt(IV) complexes; reduction of Pt(IV) to Pt(II) was not observed.
