Materials Data on NaLaTiO4 by Materials Project
NaLaTiO4 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Na1+ is bonded to five equivalent O2- atoms to form a mixture of distorted edge and corner-sharing NaO5 square pyramids. There are one shorter (2.31 Å) and four longer (2.68 Å) Na–O bond lengths. La3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of La–O bond distances ranging from 2.36–2.73 Å. Ti4+ is bonded in a 5-coordinate geometry to five O2- atoms. There is one shorter (1.76 Å) and four longer (1.95 Å) Ti–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to five equivalent La3+ atoms. In the second O2- site, O2- is bonded to five equivalent Na1+ and one Ti4+ atom to form a mixture of distorted edge and corner-sharing ONa5Ti octahedra. The corner-sharing octahedral tilt angles are 5°. In the third O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent La3+ and two equivalent Ti4+ atoms.
