Tetramethyldivinyldisilazane‐(triphenylphosphine)platinum(0) was prepared, characterized in solid state by X‐ray crystallography and in solution by multinuclear magnetic resonance spectroscopy ( 1 H, 13 C, 15 N, 29 Si, 31 P and 195 Pt NMR). Numerous signs of spin–spin coupling constants were determined by two‐dimensional heteronuclear shift correlations (HETCOR) and two‐dimensional 1 H/ 1 H COSY experiments. Isotope‐induced chemical shifts 1 Δ 12/13 C( 195 Pt) were measured from 195 Pt NMR spectra of the title compound as well as of other Pt(0), Pt(II) and Pt(IV) compounds for comparison. In contrast to other heavy nuclei such as 199 Hg or 207 Pb, the “normal” shifts of the heavy isotopomers to low frequencies are found, covering a range of >500 ppb.
