Abstract

Abstract The novel tetradentate N 3 O bifunctional agent 3-hydroxy-4-[2-(2′- pyridinecarboxamido) acetylamino] benzoic acid (1), reacts with [Bu 4 N][ReOCl 4] or [Bu 4 N][99g TcOCl 4] in EtOH resulting in neutral and stable oxorhenium 2 or oxotechnetium-99 g 3 complexes. Both complexes were characterized by elemental analysis, IR, 1 H and 13 C NMR spectroscopy. X-ray analysis of 2 showed that the rhenium atom is pentacoordinate ...
