(a) Displacement of O2 from (EMindL)Cu(O2) (2) through chemical redox, thermolysis under N2, or solvent ligation. (b) solid state structure of (EMindL)Cu(CH2Cl2) (4) at 100 K depicted at 50 % displacement ellipsoid probability. Hydrogen atoms of the ligand scaffold are omitted for clarity, excluding those on the hydrazine motif. Color scheme: Cu (cobalt blue), Cl (green), F (yellow-green), N (blue). (c) Thermal gravimetric analysis (TGA), illustrating reversible coordination of O2 under active N2 flow at 110 ºC. Color scheme denotes 2 under N2 (red) and under O2 (blue).
