title: General cooperative effects of single atom ligands on a metal: a (195)Pt NMR chemical shift as a function of coordinated halido ligands' ionic radii overall sum.
abstract: An inverse linear relationship between the experimentally observed (195)Pt NMR signals and the overall sum of coordinated halido ligands' ionic radii was discovered in Pt(ii) and Pt(iv) complexes. The reduction of (195)Pt NMR frequencies parallels the increase of coordinated halido ligands' ionic radii sum. This suggests that each halido ligand may act as a conducting ring whose induced electric current shields the (195)Pt NMR signals proportionally to the ionic radius of the coordinated halido ligand.
