The crystal data for lithium aluminogermanate, Li3AlGeO5, are Mr 200.386, orthorhombic, P21nb, a = 4.881(1), b = 5.404(3), and c = 15.841(7)Å, V = 417.9Å3, Z = 4, Dx = 3.184 g cm-3, λ(MoKα) = 0.71069Å, F(000) = 376.0, T = 298 K, R = 0.043, and Rw = 0.045 for 553 independent reflections. The structure consists of hexagonal close-packed oxide ions with cations ordered over one set of tetrahedral sites. It may also be described as a cristobalite-like sheet structure. The phases Li3AlSiO5, Li3GaSiO5, and Li3GaGeO5 are isostructural, as confirmed by Rietveld refinement.
