The structure described by NaLaSiO4 crystallizes in the orthorhombic Pnma space group. Na(1) is bonded in a 5-coordinate geometry to one O(2), two equivalent O(1), and two equivalent O(3) atoms. La(1) is bonded in a 9-coordinate geometry to two equivalent O(3), three equivalent O(2), and four equivalent O(1) atoms. Si(1) is bonded in a tetrahedral geometry to one O(2), one O(3), and two equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Na(1), two equivalent La(1), and one Si(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to one Na(1), three equivalent La(1), and one Si(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Na(1), two equivalent La(1), and one Si(1) atom. is represented by the CIF file [CIF]
