Abstract

The reaction of [TcNCl₂(PPh₃)₂] with 2,2′:6′,2″-terpyridine produced cis-[TcNCl₂(terpy)] selectively. The resulting complexes were characterized by ¹H NMR and IR spectroscopy. The geometries of the cis and trans isomers were estimated by theoretical calculations following a density functional method. The cis isomer is likely more stable than the trans one with respect to the trans influence of the nitrido ligand. Furthermore, the behavior of nitridotechnetium complexes in polar solvents was compared to Os-analogues.
