A flexible 3D porous magnet [KCo 7 (OH) 3 (ip) 6 (H 2 O) 4 ]·12 H 2 O based on unprecedented trigonal‐prismatic heptanuclear Co II clusters (see figure) is reported to undergo a reversible single‐crystal‐to‐single‐crystal transformation on the desorption/adsorption of guest molecules, accompanied by reversible magnetic property changes. This might be applied for the sensing of coordinative, paramagnetic, small molecules such as O 2 and NO.
