Article Abstract
In the presence of MeI or EtI, N-tert-butyl-1,3-thiazoline-2-thione derivatives undergo a transformation to 2-alkylthio-thiazoledithiolate pro-ligands with elimination of the tert-butyl substituent. The corresponding Au(III) dithiolene complexes [Au(RS-tzdt)2](-) (R = Me, Et) oxidize readily to the neutral radical species, such as the semi-conducting [Au(EtS-tzdt)2]˙, which organizes into dimers in the solid state.

The active sites of metalloenzymes continue to inspire synthetic chemists to create structural models of the intricate structures seen in biology. As well as the fundamental intellectual challenge, this is driven by the potential societal impact that many of these systems offer. Formate dehydrogenases (FDHs) hold such potential: formate is one of the key candidates as a hydrogen carrier for future energy transport.

Two redox-active Co(II)-radical complexes (3a and 3b), featuring a high-spin tetrahedral Co(II) ion, have been isolated as dark blue needles and remain stable in air for over a week. These complexes contain two redox non-innocent ligands (a carbene and a dithiolene), each with different coordinating atoms (two sulfur atoms and one carbon atom). Cyclic voltammetry (CV) reveals that complex 3a and 3b can form their corresponding mono-cation at potentials above -0.

Two unprecedented redox-active, low-spin Fe(III)-triradical complexes, [Fe(III)(SS-NHC═S)]·NHC═S (1·NHC═S; E═S) and [Fe(III)(SS-NHC═Se)] (2; E═Se) have been synthesized and structurally characterized by SCXRD. They were further characterized spectroscopically using IR, Raman, EPR, and UV-vis-NIR spectroscopy. The low-spin electronic configuration of the central Fe(III) ion (1) and the nature of the magnetic interaction between the Fe(III) center and the three unpaired electrons in 1 have been investigated by magnetic measurements.

Context: 1,3-Dithiola-2-thiona-4,5-dithiolate is a versatile noninnocent ligand with applications in superconductivity, magnetism, and nonlinear optical materials. This study evaluated the tris(dmit) antimony(V) and tin(IV) complexes via modern computational methods. A local energy decomposition analysis of metal‒sulfur bond formation revealed that the distorted geometry of the tris(dmit) complexes in acetonitrile is the most stable conformation for both systems, whereas other conformations remain energetically accessible.

The redox non-innocent nature of dithiolene ligands is well known for stabilizing high-valent metal ions and facilitating proton-coupled electron transfer (PCET) processes. Until now, proton reactivity at the dithiolene site has been primarily associated with low-valent metal centers, as high-valent metal-dithiolene complexes were not considered viable for such reactivity. This study introduces high-valent bis(dithiolene) tungsten (W)-oxo complexes featuring hydrogen-bonding interactions, unveiling a novel proton reduction mechanism mediated by the dithiolene moiety.
