Abstract

Sodium has been reversibly intercalated into the defect garnets Fe2(MoO4)3 and Fe2(WO4)3, yielding two new compounds, Na2Fe2(MoO4)3 and Na2Fe2(WO4)3, which retain the monoclinic symmetry of the parent compounds but with expanded unit cells. The lattice parameters for Na2Fe2(MoO4)3 are a = 16.09 Å, b = 9.507 Å, c = 18.64 Å, ß = 125.27° and for Na2Fe2(WO4)3 a = 16.16 Å, b = 9.582 Å, c = 18.80 Å, ß = 125.56°. At low sodium contents a narrow solid solution range is evident for both the tungstate and the molybdate, the structure of which is based on the parent compound. © 1990.
