NaIn(GeO3)4 crystallizes in the orthorhombic Amm2 space group. Na(1) is bonded in a 4-coordinate geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(5) atoms. In(1) is bonded to two equivalent O(2), two equivalent O(4), and four equivalent O(1) atoms to form distorted InO8 hexagonal bipyramids that share edges with eight equivalent Ge(1)O6 octahedra. Ge(1) is bonded to one O(2), one O(3), one O(4), one O(5), and two equivalent O(1) atoms to form GeO6 octahedra that share corners with six equivalent Ge(1)O6 octahedra and edges with two equivalent In(1)O8 hexagonal bipyramids. The corner-sharing octahedral tilt angles range from 22-30°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one In(1) and two equivalent Ge(1) atoms. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Na(1), one In(1), and two equivalent Ge(1) atoms. In the third O site, O(3) is bonded in a distorted T-shaped geometry to one Na(1) and two equivalent Ge(1) atoms. In the fourth O site, O(4) is bonded in a distorted T-shaped geometry to one In(1) and two equivalent Ge(1) atoms. In the fifth O site, O(5) is bonded in a distorted T-shaped geometry to one Na(1) and two equivalent Ge(1) atoms.
