摘要：
Linear and layered organically templated iron sulfates have been prepared under hydrothermal conditions. The linear iron sulfates, with the compositions [H3N(CH2)(2)NH3][FeF3(SO4)], I, [C(NH2)(3)](2)[FeF(SO4)(2)], II, [H3N(CH2)(2)NH2(CH2)(2)NH3][FeF(SO4)(2)], III, and [H2N(CH2)(4)NH2][FeF3SO4], IV, possess the chain topologies found in tancoite, butlerite, and sideronatrite minerals. The layered sulfate V, with the composition [H3N(CH2)(2)NH3][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.
