Abstract
The structure of the new phase, La24Li18.67Ti5.33O56, tetragonal, space group P4/mbm, a = 13.2443(13), c = 14.9258(20) Å, consists of alternating columns, rotated by 45° relative to each other, of perovskite-like structure, with Ti and Li in alternate octahedral sites, and twinned, distorted, zinc blende-like structure.
