Solid solutions of the form Fe II (1؊x) Fe III x O x F 2؊x have been synthesized by the reaction of FeF 2 with FeOF in a sealed platinum tube at 8503C. Careful electron probe microanalysis and X-ray powder di4raction have determined the existence of two distinct solid solution regions extending from 04x40.08 at the Fe II F 2 end and from 0.714x41 at the Fe III OF end with a miscibility gap from 0.084x40.71. Electron di4raction experiments have revealed the presence of characteristic di4use intensity distributions for samples within either solid solution region. Plausible explanations for the observed di4raction phenomena, based upon crystal chemical and bond length+bond valence arguments, are provided.
