Organically Templated Linear and Layered Iron Sulfates
Linear and layered organically templated iron sulfates have been prepared under hydrothermal conditions. The linear iron sulfates, with the compositions [H3N(CH2)2NH3]- [FeF3(SO4)], I, [C(NH2)3]2[FeF(SO4)2], II, [H3N(CH2)2NH2 (CH2)2NH3][FeF(SO4)2], III, and [H2N(CH2)4NH2] [FeF3SO4], IV, possess the chain topologies found in tancoite, butlerite, and sideronatrite minerals. The layered sulfate V, with the composition [H3N(CH2)2NH3] [Fe2F2-(SO4)2 (H2O)2], can be considered to be formed from butlerite-type chains and with a structure similar to that of the layered fluorophosphate, ULM-10. Whereas the linear chains show the presence of antiferromagnetic interactions, the layered iron sulfate exhibits metamagnetism.
