摘要：

The double sodium and iron phosphate Na3Fe(PO4)(2) was synthesized and studied by the XRD method, the second harmonic generation technique, and Mossbauer and IR spectroscopy. The compound crystallizes into a monoclinic system (space group C2/c) with unit cell parameters a = 9.0736(2) Angstrom, b = 5.0344(1) Angstrom, c = 13.8732(3) Angstrom, beta = 91.435(2)degrees and is found to be related to the K3Na(SO4)(2) structure type. The crystal structure was determined by Rietveld analysis (R-wp = 5.86, R-1 = 2.03). Iron cations occupy the M (Na) position while sodium cations occupy the X (K) and Y (K) positions of the glaserite-like structure. Mossbauer spectroscopy shows the presence of high-spin Fe3+ in octahedral coordination. (C) 2001 Academic Press.
