Abstract

A new open-framework iron(III) phosphate, I, [C₂N₂H₁₀][Fe₂(HPO₄)₄] has been hydrothermally synthesized in the presence of ethylenediamine (en). The structure is built up from the vertex linkages between the FeO₆ octahedra and the PO₄ tetrahedra, strictly alternating, forming the three-dimensional architecture. The linkages between the FeO₆ and PO₄ polyhedra gives rise to ladder-like edge-shared chains, which are connected variously forming two types of channels. The di-protonated en molecules occupy these channels. Crystal data for I, [C₂N₂H₁₀][Fe₂P₄O₁₆]: a=9.341(1), b=8.892(1), c=9.480(1) Å, ?=117.6(1)°, V=698.1(1) ų, space group P2/n (No. 13), Z=2, M=557.7, D(calc) = 2.65 g cm^-3, MoK? (?=0.71073 Å), R₁ = 0.03, wR₂ =. 0.08 and S = 1.10. Magnetic susceptibility studies indicate a predominantly antiferromagnetic interaction with T(N)=30 K.
