Stereoselective adsorption on a clay surface modified by an optically active nickel(II) tris(1,10-phenanthroline) chelate
Abstract
Adsorption of the optically active (+)510–[Fe(phen)3]2+(phen = 1, 10-phenanthroline) on a coloidal clay surface proceeds more rapidly when the surface is already occupied by the corresponding nickel chelate with the opposite chirality, (–)546–[Ni(phen)3]2+, than when it is occupied by the different enantiomer, (+)546–[Ni(phen)3]2+.
