The material structure described by Na4MgTi2(GeO5)2 crystallizes in the tetragonal P4mm space group. Na(1) is bonded in a 6-coordinate geometry to one O(3), one O(4), two equivalent O(1), and two equivalent O(2) atoms. Mg(1) is bonded in a 5-coordinate geometry to one O(3) and four equivalent O(2) atoms. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a 5-coordinate geometry to one O(4) and four equivalent O(1) atoms. In the second Ti site, Ti(2) is bonded in a distorted single-bond geometry to one O(3) and four equivalent O(2) atoms. Ge(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(2) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Na(1), one Ti(1), and one Ge(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to two equivalent Na(1), one Mg(1), one Ti(2), and one Ge(1) atom. In the third O site, O(3) is bonded in a distorted linear geometry to four equivalent Na(1), one Mg(1), and one Ti(2) atom. In the fourth O site, O(4) is bonded in a 5-coordinate geometry to four equivalent Na(1) and one Ti(1) atom. is represented by the CIF file [CIF]
