Abstract

A novel nitrido technetium complex was synthesized by the reaction of the KYCAR (lysyl-tyrosyl-cystyl-alanyl-arginine) ligand with [(n-C₄H₉)₄N][⁹⁹ TcNCl₄]. The structure of the complex was analyzed by ¹H- and ¹³C-NMR and IR spectroscopy as well as by elemental analysis. The nitrido technetium complex with KYCAR has a square pyramidal structure in which two KYCARs coordinate to the Tc atom through both an N and a deprotonated S atom of cysteine. The complex possesses a trans configuration.
