Structural and Magnetic Properties of Cu(dpa)X_2 (dpa = Di-(2-picolyl)amine; X = Cl and Br)

摘要

Di-(2-picolyl)amine (dpa) can coordinate with transition metal ions through an amine nitrogen as well as two pyridine nitrogens and act as a tridentate ligand. The transition metal complexes with dpa or substituted-dpa ligand continue to be interest in many fields in chemistry. For example, carbohydrate-appended dpa metal complexes were suggested as potential imaging agents and sugar-pendant dpa Cu(II) complexes were used to regulate chirality on the copper coordinated oxygen atom. Zinc-dpa complexes were applied to fluorescent chemsensors toward a phosphrory-lated peptide surface.
