摘要

The hydrothermal synthesis and structure for a new iron phosphate based open-framework solid, (NH₄)[Fe₂(OH)(H₂O) (PO₄)₂]·1.5H₂O, is presented. The three-dimensional (3-D) framework is built from butterfly-shaped tetranuclear iron-oxygen clusters, which are coordinated by eight PO₄ tetrahedra to create 8-membered windows along the a-, b- and c-axes; the lattice water molecules as well as the counter NH₄⁺ cations reside in the cross channels. The new open-framework solid is a pseudo-polymorph with the known structure of the mineral sphenicidite, and exhibits spontaneous magnetization in the low temperature regime with T_N ≈ 25 K, which is a result of canted spin antiferromagnetism.
