About this Chemistry article
Rhenium and technetium complexes with tridentate S,N,O ligands derived from benzoylhydrazine by Hung Huy Nguyen; Ulrich Abram is a Chemistry article available to read on EtoBox.
A potentially tridentate ligand with an S,N,O donor set, H 2 L, is formed by the reaction of N-[(diethylaminothiocarbonyl)benzimidoyl chloride with benzoylhydrazine. Reactions of H 2 L with (NBu 4 )[MOCl 4 ] complexes (M = Re, Tc) give five-coordinate, neutral oxo complexes of the composition [MOCl(L)]. Mixed-ligand complexes of rhenium(V) containing the tridentate L 2À ligand and bidentate N,N-dialkyl-N 0 -benzoylthioureato ligands (R 2 btu À ) are formed in high yields when (NBu 4 )[ReOCl 4 ] is treated with mixtures of H 2 L and HR 2 btu. Another approach to the mixed-ligand products is the reaction of [ReOCl(L)] with an equivalent amount of HR 2 btu.
