text: Coupling of Pt to H, C, P, F or N has been reported through one up to four bonds (J to J) and is commonly studied to provide additional structural information for platinum complexes. The ~34% abundance of Pt (with the remaining 66% of natural Pt being NMR-inactive) means that this coupling appears in the respective H/P/N/C NMR spectra as satellite peaks (cf. C satellites) which, for example, result in 17:66:17 patterns for singlets.
  The trans influence in 16 e square planar Pt complexes has been studied by comparing the magnitude of coupling constants in the cis- and trans- isomers.
  Complicated homonuclear couplings ranging from 60 to 9000 Hz for J(Pt–Pt) are of interest in the context of platinum cluster compounds.
