Crypt analysis : The reaction of manganese( II ) chloride with sodium hydroxide, di‐(2‐pyridyl)‐ketonoxime, and sodium azide yields a metallacryptate consisting of 26 manganese centers, namely, four Mn II (see picture; gold spheres) and 22 Mn III ions (green, aqua, and blue spheres). Results obtained from ac SQUID magnetic studies indicate that this molecule displays single‐molecule magnetic behavior.
