Reaction of the deprotonated N-thiophosphorylated thiourea o-MeO(O)CC 6H4NHC(S)NHP(S)(OiPr)2 (HL) with Co II leads to the [CoL2] complex, the structure of which was studied by IR, UV-Vis, diffuse reflectance and NMR spectroscopy, ESI +/- mass spectrometry and microanalysis. The thermal properties of [CoL2] in an air atmosphere were studied by means of simultaneous TG/DTA analyses with the observed unprecedented final residue corresponding to CoPS3. Investigation of the thermal dependence of the magnetic susceptibility has shown that [CoL2] behaves as a spin-canted ferromagnet. The molecular structures of [CoL2] at 100 and 173 K were elucidated by a single crystal X-ray diffraction analysis. The metal was found to be in a tetrahedral 1,5-S2S′2 environment formed by the C=S and P=S sulfur atoms.
