variety of rhenium(III) or (V) precursors with the bidentate (1−) mixed phosphino-thiol ligand 2-(diphenylphosphino)benzenethiol (DPPBTH) in mildly alkaline methanol leads to the formation of the 16-electron complex [Re(DPPBT)3] (I). With technetium [Tc(DPPBT)3] (II), [TcOCl(DPPBT)2] (III) or [TcN(DPPBT)2] (IV) may be obtained depending on the conditions and starting material. The X-ray crystal and molecular

A highly selective chemiresistive ethylene sensor based on reversible and selective ligand-centered substrate binding to a metal-stabilized thiyl radical has been developed. The solid-state device efficiently differentiates between ethylene and other alkene analytes. The sensor is prepared by simple dropcast deposition of the complex as a film across a microgap gold electrode.
