The first examples of layered hybrid iron fluorides are reported. In the reactions carried out, the chain compound (H2pipz)FeF5·H2O always occurs as the major phase, with the layered compounds, (H2pipz)3Fe4F18·2H2O and (H2pipz)2Fe3F13·H2O, being isolated from some reactions as major impurities. The latter two compounds feature two-dimensional sheets of corner-and edge-shared FeIIIF6 octahedra, resulting in two distinct layer architectures. The compound (H2pipz)FeF5·H2O, isolated as the major phase, crystallises with a one-dimensional structure exhibiting zig-zag [FeF5]∞ chains. This work opens up the potential for a much wider family of layered hybrid transition-metal fluorides.
