The crystal and magnetic structures of the organic–inorganic layer compound phenylphosphonato-Mn(II)-hydrate: A synchrotron X-ray and neutron powder diffraction study

The crystal and magnetic structures of the organic–inorganic layer compound phenylphosphonato-Mn(II)-hydrate, C6D5PO3Mn⋅D2O, have been studied by powder diffraction using synchrotron X-rays and neutrons. The crystal structure is resolved by both techniques including orientational disorder of the phenyl-groups. Temperature-dependent neutron diffraction peaks below 12 K are identified as magnetic in origin; their indices show that the magnetic structure is closely similar to that of KMnPO4⋅H2O.
