The 1H NMR, IR and electronic spectra are reported for a range of complexes trans- comprising fifteen variously-substituted anilines, R-an.The coupling constant, JPt-H, is approximately 64 Hz which is consistent with trans coordination.The chemical shift of the olefinic protons is relatively unaffected by variation of R but the shielding of the aromatic protons is slightly modified.All three infrared modes νPt-C2, νPt-N and νC-C (olefin) are simultaneously increased by electron-releasing substituents showing that the electronic effects of R are transmitted throughout the complex molecule.The UV spectra show that the ? -> ?* transition within the aniline ring is the electronic band of maximum sensitivity to R.
