The magnetic properties of O2 adsorbed in the microporous coordination polymer Cd(bpndc)(bpy) were investigated by means of high-field magnetization measurement. The magnetization of adsorbed O2 has a paramagnetic-like behavior in the low-field region and increases steeply above 50 T. The experiment results suggest that the half of adsorbed O2 that forms O2–O2 dimer causes the metamagnetic-like behavior and the remaining O2 causes paramagnetic-like behavior owing to nearly isolated spin. A possible arrangement of O2 is suggested.
