Crystal structure of spinel-type Li(0.64)Fe(2.15)Ge(0.21)O(4)

Spinel-type Li(0.64)Fe(2.15)Ge(0.21)O(4), lithium diiron(III) germanium tetra­oxide, has been formed as a by-product during flux growth of an Li–Fe–Ge pyroxene-type material. In the title compound, lithium is ordered on the octa­hedral B sites, while Ge(4+) orders onto the tetra­hedral A sites, and...

Sumario:Spinel-type Li(0.64)Fe(2.15)Ge(0.21)O(4), lithium diiron(III) germanium tetra­oxide, has been formed as a by-product during flux growth of an Li–Fe–Ge pyroxene-type material. In the title compound, lithium is ordered on the octa­hedral B sites, while Ge(4+) orders onto the tetra­hedral A sites, and iron distributes over both the octa­hedral and tetra­hedral sites, and is in the trivalent state as determined from Mössbauer spectroscopy. The oxygen parameter u is 0.2543; thus, the spinel is close to having an ideal cubic closed packing of the O atoms. The title spinel is compared with other Li- and Ge-containing spinels.
