A perfect Kagomé lattice is displayed by the mixed‐valent layered structure of [HN(CH 2 ) 6 NH][Fe III Fe $\rm{^{{II}}_{{2}}}$ F 6 (SO 4 ) 2 ]⋅[H 3 O] (see picture), in which 100 % of the iron sites are occupied. The complex exhibits unusual magnetic properties; both magnetic frustration and ferrimagnetic behavior are observed.
