Abstract

^1^H, ^13^C and ^15^N nuclear magnetic resonance studies of gold(III), palladium(II) and platinum(II) chloride complexes with phenylpyridines (PPY: 4‐phenylpyridine, 4ppy; 3‐phenylpyridine, 3ppy; and 2‐phenylpyridine, 2ppy) having the general formulae [Au(PPY)Cl~3~], trans‐/cis‐[Pd(PPY)~2~Cl~2~] and trans‐/cis‐[Pt(PPY)~2~Cl~2~] were performed and the respective chemical shifts (δ, δ and δ) reported. ^1^H, ^13^C and ^15^N coordination shifts (i.e. differences between chemical shifts of the same atom in the complex and ligand molecules: $\Delta_{\rm {coord}}^{1_{\rm {H}}} = \delta_{\rm {complex}}^{1_{\rm {H}}} - \delta_{\rm {ligand}}^{1_{\rm {H}}}$, $\Delta_{\rm {coord}}^{13_{\rm {C}}} = \delta_{\rm {complex}}^{13_{\rm {C}}} - \delta_{\rm {ligand}}^{13_{\rm {C}}}$, $\Delta_{\rm {coord}}^{15_{\rm {N}}} = \delta_{\rm {complex}}^{15_{\rm {N}}} - \delta_{\rm {ligand}}^{15_{\rm {N}}}$) were discussed in relation to the type of the central atom (Au(III), Pd(II) and Pt(II)), geometry (trans‐/cis‐) and the position of a phenyl group in the pyridine ring system.
