NaLaSiO4 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. there are three inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Na–O bond distances ranging from 2.40–2.94 Å. In the second Na1+ site, Na1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Na–O bond distances ranging from 2.39–2.58 Å. In the third Na1+ site, Na1+ is bonded in a 4-coordinate geometry to nine O2- atoms. There are a spread of Na–O bond distances ranging from 2.43–3.11 Å. There are three inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.44–2.65 Å. In the second La3+ site, La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.44–2.70 Å. In the third La3+ site, La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.40–2.76 Å. There are three inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Si–O bond distances ranging from 1.64–1.66 Å. In the second Si4+ site, Si4+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.65 Å) and two longer (1.66 Å) Si–O bond length. In the third Si4+ site, Si4+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.64 Å) and two longer (1.65 Å) Si–O bond length. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to one Na1+, two equivalent La3+, and one Si4+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Na1+, two La3+, and one Si4+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two Na1+, two La3+, and one Si4+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two Na1+, two La3+, and one Si4+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to one Na1+, two La3+, and one Si4+ atom. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to one Na1+, two La3+, and one Si4+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to one Na1+, two La3+, and one Si4+ atom. In the eighth O2- site, O2- is bonded in a 1-coordinate geometry to two Na1+, two La3+, and one Si4+ atom. In the ninth O2- site, O2- is bonded in a 1-coordinate geometry to two Na1+, two La3+, and one Si4+ atom. In the tenth O2- site, O2- is bonded in a 1-coordinate geometry to one Na1+, two La3+, and one Si4+ atom. In the eleventh O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Na1+, two La3+, and one Si4+ atom. In the twelfth O2- site, O2- is bonded in a distorted single-bond geometry to two Na1+, two La3+, and one Si4+ atom.
