“…The bond distances and bond angles are given in the Table . The Co–S bond distances (2.24–2.28 Å) are in good agreement with other reported low spin Co(III)–thiolato complexes, and the Co–N bond distances (1.95–1.96 Å) and N–Co–S bond angles (72.3–72.6 deg) are also in good agreement with other low-spin Fe and Ni pyridine thiolate complexes. − …”

The chemical and electrochemical reduction of CO2 to value added chemicals entails the development of efficient and selective catalysts. Synthesis, characterization and electrochemical CO2 reduction activity of a air-stable cobalt(III) diphenylphosphenethano-bis(2-pyridinethiolate)chloride [{Co(dppe)(2-PyS)2}Cl, 1-Cl] complex is divulged. The complex reduces CO2 under homogeneous electrocatalytic conditions to produce CO with high Faradaic efficiency (FE > 92%) and selectivity in the presence of water. Through detailed electrochemical investigations, product analysis, and mechanistic investigations supported by theoretical calculations, it is established that complex 1-Cl reduces CO2 in its Co(I) state. A reductive cleavage leads to a dangling protonated pyridine arm which enables facile CO2 binding through a H-bond donation and facilitates the C–O bond cleavage via a directed protonation. A systematic benchmarking of this catalyst indicates that it has a modest overpotential (∼180 mV) and a TOF of ∼20 s–1 for selective reduction of CO2 to CO with H2O as a proton source.

“…In our previous work, we synthesized complex Cp * CoI(2-PyS) in a very high yield, which was used as a starting material to study the reaction with monodentate or bidentate 1,2-dicarba-closo-dodecaborane thiolate, 2-pyridinethiolate, 2-pyridinethione, 4-pyridinethiolate and benzenethiolate ligands and some interesting phenomena were detected, such as C-H activation reaction [25,26] (2) or Cp * CoI(2-TaS) (3) was isolated as green crystals in about 80% yield, respectively (Scheme 1). Complexes 1, 2 and 3 are all a little air sensitive and soluble in common organic solvents, such as CH 2 Cl 2 and THF.…”

2 ], where M = Co(II) or Cu(II) and L is the ligand. Also, reaction of an aqueous ethanolic solution of Co(Ac) 2 ·2H 2 O with the previous ligands was prepared. Elemental analysis, and infrared and electronic spectral data are presented to confirm the formulation of the amorphous complexes. The spectral data indicate that the ligands are coordinated to the metal via the thioenol sulfur atom and the nitrogen atom of cyano groups. The ligands reacts in the enol form through the anodic dissolution of the ligands or during the reaction with metal salts. The ligand field parameters and crystal field splitting energies, o , for different cobalt metal complexes were calculated.
