Two ambient-temperature molecule-based magnets (Curie temperatures Tc of ∼350 K and 372 K) are presented, which are the result of research to identify factors in synthesis that control the magnetic properties of compounds. The goal is to increase Tc. The magnetic properties of the two hexacyanochromate magnets are described (see also the cover of this issue) and the reasons for the differences between them and earlier hexacyanochromate magnets (Tc ∼ 315 K) are discussed. High Curie temperature materials may find applications in magnetic shielding and memory storage devices, for example.
