Abstract

^1^H, ^13^C, ^195^Pt and ^15^N NMR studies of platinide(II) (M = Pd, Pt) chloride complexes with such alkyl and aryl derivatives of 2,2′‐bipyridine and 1,10‐phenanthroline as LL = 6,6′‐dimethyl‐bpy, 5,5′‐dimethyl‐bpy, 4,4′‐di‐tert‐butyl‐bpy, 2,9‐dimethyl‐phen, 2,9‐dimethyl‐4,7‐diphenyl‐phen, 3,4,7,8‐tetramethyl‐phen, having the general [M(LL)Cl~2~] formula were performed and the respective chemical shifts (δ^1H^, δ^13C^, δ^195Pt^, δ^15N^) reported. ^1^H high‐frequency coordination shifts ($\Delta_{\rm {coord}}^{\rm {1H}} = \delta_{\rm {complex}}^{\rm {1H}} - \delta_{\rm {ligand}}^{\rm {1H}}$) mostly pronounced for nitrogen‐adjacent protons and methyl groups in the nearest adjacency of nitrogen, as well as ^15^N low‐frequency coordination shifts ($\Delta_{\rm {coord}}^{\rm {15N}} = \delta_{\rm {complex}}^{\rm {15N}} - \delta_{\rm {ligand}}^{\rm {15N}}$) were discussed in relation to the molecular structures.
