Magnetic Properties and the Arrangement of Molecular Oxygen Adsorbed in the Microporous Coordination Polymer Cd(bpndc)(bpy)
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.
