Organically Templated Mixed-Valent Iron Sulfates Possessing Kagomé and Other Types of Layered Networks

Abstract

A perfect Kagomé lattice is displayed by the mixed-valent layered structure of [HN(CH2)6NH][FeIIIFeF6(SO4)2]⋅[H3O] (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.
