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 HydroxylâM2+ Interaction in Complexes of Hydroxymethylphosphonate Metal-IonâGlycerol 1-Phosphate Systems: A Decreasing Solvent Polarity Favors HydroxylâM2+ 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+âCarboxylate 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 HydroxylâMetal-Ion Interaction Decreasing Solvent Polarity Favors the HydroxylâMetal-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 RCH2âNH2 Ligands Extent of Hydroxyl GroupâMetal-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 HydroxylâMetal-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 HydroxylâMetal-Ion Interaction Extent of HydroxylâMetal-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-IonâHydroxyl 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 Conclusion
