Breathtaking are the highly magnetic and porous vanadocarboxylates ( T N =95 K) MIL‐47as (left) and evacuated MIL‐47 (right) that exhibit three‐dimensional large‐pore structures built up from infinite chains of corner‐sharing V III O 4 (OH) 2 (MIL‐47as) and V IV O 6 (MIL‐47) octahedra linked by rigid terephthalate anions. The reversible adsorption–desorption corresponds to a breathing of the structure. The high T N value results from the combination of magnetic chains with the presence of the π electrons of the terephthalate.
