Popis:	N, N, N', N'-Tetrakis-(n-propyl)-1,2-phenylenedioxydiacetamide and related ligands with four binding sites have been shown to selectively complex Group IIA cations in solution via liquid membrane, picrate extraction, and UV spectroscopic techniques. The formation and partial characterization of crystalline complexes of these ligands with various salts of Group IIA, transition metal and rare earth cations is reported. The complexes were characterized by IR and UV spectroscopy, molar electrolytic conductance, elemental analysis, and (in several cases) single crystal X-ray analysis. The accumulated evidence suggests that [L2M]2+[MX4]2- (X = Cl, Br, SCN), [L2M]2+2X− (X = Cl, Br, SCN, BF4, ClO4) or [LM]2+2X− (X = Cl, Br, SCN) complexes are formed. The [L2M]2+ complexes are eight-coordinate in some cases. Thus these ligands can vary their stoichiometry of complexation depending upon the cation and anion involved. Trans-N, N, N', N,-tetrakis-(n-propyl)-1, 2-cyclohexanedioxydiacetamide reacts with MnBr2 ...
