Fridge magnet : A decametallic mixed‐valent Mn supertetrahedron (see picture; M purple, O red, N blue, Br brown, C gray) displays dominant ferromagnetic exchange and a spin ground state of S =22. The magnetic behavior of the cluster makes it suitable for use as a low‐temperature magnetic refrigerant.
