The crystal structure described by Na2InSiO5 crystallizes in the orthorhombic Pnma space group. Na(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. In(1) is bonded in a 8-coordinate geometry to one O(2), one O(3), two equivalent O(4), 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 four inequivalent O sites. In the first O site, O(4) is bonded in a 6-coordinate geometry to four equivalent Na(1) and two equivalent In(1) atoms. In the second O site, O(1) is bonded in a 5-coordinate geometry to two equivalent Na(1), two equivalent In(1), and one Si(1) atom. In the third O site, O(2) is bonded in a 6-coordinate geometry to four equivalent Na(1), one In(1), and one Si(1) atom. In the fourth O site, O(3) is bonded in a 6-coordinate geometry to four equivalent Na(1), one In(1), and one Si(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
