The reaction of cobalt powder with iodine activated by tetraphenyldithioimidodiphosphorane (Ph 2 P(S)NHP(S)Ph 2 ) ( L H) gives the complex Co L 2 ( 1 ). Its solid‐state structure [triclinic, space group P1 (No. 2), Z = 2, a = 13.321(2) Å, b = 13.872(2) Å, c = 14.394(3) Å, α = 82.500(10)°, β = 65.950(10)°, γ = 69.640(10)°] comprises discrete, monomeric molecules where a Co II ion is coordinated to four sulphur atoms by two bidentate anionic ligands L in a distorted tetrahedral CoS 4 core. The electrochemistry of L H · I 2 and Co L 2 has been studied by cyclic voltammetry. FT‐IR, Raman, 31 P‐NMR spectroscopies, are in accordance with the structural features of the complex. Hybrid‐DFT calculations have been used to gain an insight on the π properties of L H and L .
