Three new N2S2 donor ligands 1, 1′-((2-(2-(phenylthio) phenylthio) phenyl) methylene) bis (3, 5-R-1H-pyrazole), R= H (LH), R= Me (LMe), R= i-Pr (Li-Pr) have been prepared and characterized. These bifunctional ligands incorporate two distinct chelate donor systems, by virtue of the presence of bispyrazole and bisthioether functions. The preferred conformation of these ligands is such that the N2 and S2 donor moieties may be oriented in opposite ...
