Isolation and oxygen activation of electron-rich CoII4O metallic clusters having a 3-fold symmetry
Two novel atomically precise tetra-nuclear cobalt clusters (3a-3b) having a CoII4O core with 3-fold symmetry, and three short Co-Co distances of 2.7046(4) Å are isolated with three chelating NP-donor mono-anionic ligands. 3a-3b are shown to react with O<sub>2</sub>, producing dinuclear cobalt complexes (4a-4b), where the P-centres of the ligands are oxygenated. All complexes are structurally characterized by single-crystal X-ray diffraction, and further studied by UV-vis, IR spectroscopy, CV, magnetic susceptibility measurements, and DFT calculations.
