摘要
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. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
