摘要：

HLiTa3O8 crystallizes in the orthorhombic system with unit-cell dimensions (from single crystal date) a = 16.702(8), b = 3.840(4), c = 8.929(5) Å, and space group Pmma, z = 4. The structure was solved by analogy with the structure of LiNb6O15F and refined by Fourier and least-squares refinement techniques. Of the 983 unique reflections measured by counter techniques, 739 with I ≥ 3σ(I) were used in the least-squares refinement of the model to a conventional R of 0.060 (Rw = 0.067). HLiTa3O8 has the same basic structure as the compounds LiNb6O15F, β-Ta3O7F and Nb2WO8; its relationship to these and other structures is discussed. © 1979.
