Three kinds of platinum(II) complexes, 2(PPh3)2>(hfac)2, <(PPh3)2>X (2; R=Et or H, X=hfac) and <(PPh3)2> (R=Et (3a) or H), containing thiourea derivatives as neutral, monoanionic, and dianionic ligands, respectively, have been prepared.Thioureido(1-) complex 2 (R=Et, X=OTs) was also prepared by protonation of 3a with TsOH*H2O.The structure of 3a with an N,S-chelating thioureido(2-)ligand was determined by single-crystal X-Ray diffraction.
