N2 - High-resolution 13C n.m.r. spectra were measured for platinum, palladium, and nickel dithioacetato complexes with various structures and oxidation states in the solid state. The [Pt2(S2CMe)4] complex showed one methyl signal, while [Ni2(S2CMe)4] and [Pd2(S2CMe)4] showed two and three methyl signals, respectively. These results are well explained in terms of the single-crystal X-ray structures of these complexes. Compared with the spectrum of [Pt2(S2CMe)4], the quaternary carbon signal of [Pt2(S2CMe)4I2] is shifted to lower-field, while the methyl signal appears at a similar position, indicating the greater effectiveness of Pt3+ over Pt2+ in removing electron density from the surrounding quaternary carbon atoms. The one-dimensional [M2(S2CMe)4I] (M = Ni or Pt) complexes showed two broad methyl signals owing to the slight magnetism.
