✦ Synopsis

Paramagnetic gas molecules with a 3 S g À ground state, of which oxygen is the simplest and most stable, exhibit interesting magnetic properties when incorporated into clathrate compounds. [1] The unusual paramagnetic behavior of included oxygen in a 1D channel of a metal-organic gas adsorbent was reported by Mori et al. in 1997, [2] and caught the attention of theoreticians [3] owing to the interest in oxygen-based Haldane systems. [4] The report, together with the worldwide growth of synthetic studies of gas-adsorbing crystalline microporous metal-complex systems, [5] inspired an analogous experiment by Kitaura et al. in 2002, [6] in which a microporous copper coordination polymer was used as host. In contrast, we
