Iron arsenate frameworks
Six new iron arsenate framework structures, Fe2As2O7·2H2O, [Fe6As8O32H4]2–(1,4-butanediamininium2+)·2H2O, [Fe4As6O22H2]2–(piperazinium2+), [Fe5As5O24H4]2–(piperazinium2+)·2H2O, [Fe6As7O31H5]2–(dabco2+) and LiFeAsO4OH have been synthesised under hydrothermal conditions. Incorporation of the amine cation templates leads to more open framework geometries and, in contrast to iron phosphates which have topologies based on PO4 tetrahedra, the iron arsenate structures typically contain protonated As(O,OH)4 units. The magnetic properties of the iron arsenates studied show Curie–Weiss behaviours with maxima in the (T) vs.T plots in the range 10–50 K.

Abstract
Six new iron arsenate framework structures, Fe2As2O7·2H2O, [Fe6As8O32H4]2–(1,4-butanediamininium2+)·2H2O, [Fe4As6O22H2]2–(piperazinium2+), [Fe5As5O24H4]2–(piperazinium2+)·2H2O, [Fe6As7O31H5]2–(dabco2+) and LiFeAsO4OH have been synthesised under hydrothermal conditions. Incorporation of the amine cation templates leads to more open framework geometries and, in contrast to iron phosphates which have topologies based on PO4 tetrahedra, the iron arsenate structures typically contain protonated As(O,OH)4 units. The magnetic properties of the iron arsenates studied show Curie–Weiss behaviours with maxima in the (T) vs.T plots in the range 10–50 K.
