Abstract
NaLa2Ti2MnO9 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 11-coordinate geometry to eleven O2- atoms. There are a spread of Na–O bond distances ranging from 2.46–2.97 Å. In the second Na1+ site, Na1+ is bonded in a 12-coordinate geometry to seven O2- atoms. There are a spread of Na–O bond distances ranging from 2.43–2.81 Å. There are four inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 12-coordinate geometry to five O2- atoms. There are a spread of La–O bond distances ranging from 2.41–2.55 Å. In the second La3+ site, La3+ is bonded in a 11-coordinate geometry to five O2- atoms. There are a spread of La–O bond distances ranging from 2.40–2.56 Å.
