Probing the Metal-Ion-Binding Strength of the Hydroxyl Group

Introduction How Is the Extent of a Weak Interaction Best Quantified? Metal-Ion Complexes with Phosph(on)ate Groups as Primary Binding Sites Extent of the Hydroxyl−M2+ Interaction in Complexes of Hydroxymethylphosphonate Metal-Ion−Glycerol 1-Phosphate Systems: A Decreasing Solvent Polarity Favors Hydroxyl−M2+ Interactions Some Generalizations Regarding Phosph(on)ate Ligands with a Weakly Coordinating Second Site Metal-Ion Complexes with Carboxylate Groups as Primary Binding Sites Extent of Chelate Formation in Complexes of Hydroxyacetate and Related Ligands at I = 0.1 M Construction of the Reference Lines for Several M2+−Carboxylate Systems. Extent of Chelate Formation in Metal-Ion Complexes Formed with Hydroxy Carboxylates and Related Ligands Extent of Chelate Formation in Complexes of Hydroxyacetate-Type Ligands at I = 2 M Effect of Chelate-Ring Enlargement on the Hydroxyl−Metal-Ion Interaction Decreasing Solvent Polarity Favors the Hydroxyl−Metal-Ion Interaction in Complexes of Hydroxyacetate and Related O Ligands But Inhibits Thioether Interactions Metal-Ion Complexes with Amino Groups as Primary Binding Sites Estimation of Straight-Line Parameters for Complexes Formed with RCH2−NH2 Ligands Extent of Hydroxyl Group−Metal-Ion Binding in Complexes of 2-Aminoethanol and Related Ligands Comparison of the Metal-Ion-Binding Properties of 2-Aminoethanol and Triethanolamine Imidazole Residue as a Primary Binding Site in Ligands Containing also a Hydroxyl Group Pyridyl Nitrogen Is an Ideal Primary Metal-Ion-Binding Site for a Hydroxyl−Metal-Ion Interaction Isomeric Quantification of Metal-Ion Binding with Ligands Offering Two Hydroxyl Groups Effect of the Primary Binding Site on the Extent of the Hydroxyl−Metal-Ion Interaction Extent of Hydroxyl−Metal-Ion Interactions in Complexes Having a Bidentate Primary Binding Site Metal-Ion Complexes of Ligands with Two or More Hydroxyl Groups and at Least Four Binding Sites Complexes of the Alkaline EarthIons with Bistris and Some Related Buffers: Reduced Solvent Polarity Favors Metal-Ion−Hydroxyl Group Interactions Complexes of Several 3d and Related Metal Ions with Bistris and Derivatives Quest for Selectivity in Metal-Ion Coordination Involving Hydroxyl Groups General Conclusions
