Study of Pt(II)-aromatic amines complexes of the types cis- and trans-Pt(amine)2I2, [Pt(amine)4]I2 and I(amine)Pt(μ-I)2Pt(amine)I

Pt(II) complexes of the types cis- and trans-Pt(amine)2I2 with amines containing a phenyl group were synthesized and studied mainly by IR and multinuclear (195Pt, 1H and 13C) magnetic resonance spectroscopies. The compounds are not very soluble. In 195Pt NMR spectroscopy, the cis isomers were observed at slightly lower fields than the trans analogues (average Δδ = 11 ppm) in acetone. In 1H NMR, the NH groups were also found at slightly lower fields in the cis isomers. The coupling constants 2J(195Pt-1HN) varied from 53 to 85 Hz and seem slightly smaller in the trans configuration. The 13C NMR spectra of most of the complexes were measured. No coupling constants J(195Pt-13C) were detected due to the low solubility of the compounds. The cis isomers containing a phenyl group on the N atom could not be isolated except for Ph-NH2 which was shown to be a mixture of isomers in acetone. The tetrasubstituted ionic compounds [Pt(amine)4]I2 for the less crowded ligands were also studied mainly by NMR spectroscopy in aqueous solution. The 195Pt chemical shifts vary between -2855 and -2909 ppm. The coupling constants 3J(195Pt-1H) are about 40 Hz. The iodo-bridged dinuclear species I(amine)Pt(μ-I)2Pt(amine)I were also synthesized and characterized. Two isomers are present in acetone solution for most of the compounds. Their δ(Pt) signals were observed at about -4000 ppm and their coupling constants 2J(195Pt-1HN) are around 69 Hz.

THE INFRARED SPECTRA OF ANILINE COMPLEXES OF PLATINUM(II) HALIDES AND NITRITE

The infrared spectra (4000-90 cm-1) of the complexes cis- and trans- (an=aniline; X=Cl, Br, I, NO2) and their aniline-d5 analogues are determined.For the complexes cis- and trans-, the spectra of the 15N-labelled species
