Hydrothermal synthesis, crystal structures, and magnetic properties of a novel three-dimensional iron phosphite: image

A three-dimensional iron phosphite, image, has been synthesized under mild hydrothermal conditions and characterized by single crystal X-ray diffraction. The compound crystallizes in the monoclinic space group P21/c, with unit cell parameters, a = 12.4397(3) Å, b = 10.1642(3) Å, c = 9.3201(3) Å, and Z = 4. The compound forms three-dimensional framework with six-membered channels along the c-axis. The Fe center in the framework adopts slightly distorted octahedral coordination geometry and is bridged by the pseudo-pyramidal phosphites. Magnetic measurement indicates the anti-ferromagnetic interactions in the title compound.
