The study of Gd3+ complexation with 4-dihydroxyboropenylalanine in aqueous solutions

The process of Gd 3+ complexation with 4-dihydroxyborophenylalanine (DHBPA) in aqueous solutions was studied by the contact conductometry, IR, and X-ray photoelectronic spectroscopy methods. The complex formation reactions of Gd 3+ with DHBPA were found to occur in steps, depending on the metal: lig...

Description
Summary:The process of Gd 3+ complexation with 4-dihydroxyborophenylalanine (DHBPA) in aqueous solutions was studied by the contact conductometry, IR, and X-ray photoelectronic spectroscopy methods. The complex formation reactions of Gd 3+ with DHBPA were found to occur in steps, depending on the metal: ligand ratio. In the final reaction product, i.e., the chelate complex [Gd(DHBPA) 3 ], each molecule of a ligand occupies two coordination sites.
