The crystal structure described by Y3GeO8 crystallizes in the monoclinic P2_1/m space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 7-coordinate geometry to one O(2), two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms. In the second Y site, Y(2) is bonded in a 8-coordinate geometry to one O(2), one O(5), two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms. Ge(1) is bonded in a distorted trigonal bipyramidal geometry to one O(5), two equivalent O(1), and two equivalent O(4) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded to one Y(2), two equivalent Y(1), and one Ge(1) atom to form a mixture of corner and edge-sharing OY3Ge tetrahedra. In the second O site, O(2) is bonded in a trigonal non-coplanar geometry to one Y(2) and two equivalent Y(1) atoms. In the third O site, O(3) is bonded in a trigonal non-coplanar geometry to one Y(2) and two equivalent Y(1) atoms. In the fourth O site, O(4) is bonded to one Y(2), two equivalent Y(1), and one Ge(1) atom to form a mixture of corner and edge-sharing OY3Ge tetrahedra. In the fifth O site, O(5) is bonded in a distorted linear geometry to one Y(2) and one Ge(1) atom. is represented by the CIF card [CIF]
