Description
Summary:Mixed-ligand metal-polymer complexes (MPC) of N-vinylpyrrolidone-N-vinylformamide-N-vinyl iminodiacedic acid (VP-VFA-VIDA) copolymers and diethyldithiocarbamate (DEDTC) as a co-ligand with indium were synthesized under mild conditions and pH close to physiological values. Isolated MPC were characterized by UV, IR, 1H NMR, atomic absorption spectrophotometry, and HPLC. The obtained data implied that the MPC contain 8-10 wt% of (IDA)In(DEDTC) fragments. The optimal conditions for radiochemical synthesis of VP-VFA-VIDA-111In-(DEDTC) metal-polymer complex with mixed ligands were defined. The closest coordination environment of 111In was studied by perturbed angular correlation technique. The obtained data are in good agreement with the information about weight amounts of the corresponding indium MPC.
