The magnetic properties of O 2 adsorbed in the microporous coordination polymer Cd(bpndc)(bpy) were investigated by means of high-field magnetization measurement. The magnetization of adsorbed O 2 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 O 2 that forms O 2-O 2 dimer causes the metamagnetic-like behavior and the remaining O 2 causes paramagnetic-like behavior owing to nearly isolated spin. A possible arrangement of O 2 is suggested.
