Molecule‐based magnets with high ordering temperatures T c (above room temperature) include some mixed‐oxide hexacyanometallates. The example studied here, Cr 2.12 (CN) 6 · ½ H 2 O (the Figure shows its crystalline and amorphous phases), is shown to have T c equals; 260 K and exhibit negative (reverse) magnetization. An explanation is suggested for this behavior and the temperature and field dependences of the magnetization.
