Nanoporous magnetic materials composed of metal‐assembled complexes are expected to exhibit chemical sensitivity. In this work, we observed a humidity‐induced reversible change between ferromagnetism and antiferromagnetism in a new type of a cobalt octacyanoniobate based magnet in the high‐humidity region. This humidity response is caused by the adsorption and desorption of non‐coordinated water (so‐called zeolitic water) molecules in the interstitial site. Such a phenomenon is achieved by the structural flexibility of an octacyanometalate‐based magnet.
