The structure described by NaEu(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(4) atoms. Eu(1) is bonded in a 10-coordinate geometry to two equivalent O(3), four equivalent O(1), and four equivalent O(5) atoms. 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 corner-sharing GeO6 octahedra. The corner-sharing octahedral tilt angles range from 19-35°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Eu(1) and two equivalent Ge(1) atoms. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Na(1) and two equivalent Ge(1) atoms. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Na(1), one Eu(1), and two equivalent Ge(1) atoms. In the fourth O site, O(4) is bonded in a distorted T-shaped geometry to one Na(1) and two equivalent Ge(1) atoms. In the fifth O site, O(5) is bonded in a 4-coordinate geometry to two equivalent Eu(1) and two equivalent Ge(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
