The material described by Ga2B3O8 crystallizes in the orthorhombic Cmce space group. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to one O(3), one O(5), two equivalent O(2), and two equivalent O(4) atoms to form GaO6 octahedra that share corners with two equivalent B(2)O4 tetrahedra, corners with six equivalent B(1)O4 tetrahedra, and edges with two equivalent Ga(2)O6 octahedra. In the second Ga site, Ga(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(5) atoms to form GaO6 octahedra that share corners with two equivalent B(2)O4 tetrahedra, corners with four equivalent B(1)O4 tetrahedra,  an edgeedge with one Ga(2)O6 octahedra, and edges with two equivalent Ga(1)O6 octahedra. There are two inequivalent B sites. In the first B site, B(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form BO4 tetrahedra that share corners with two equivalent Ga(2)O6 octahedra, corners with three equivalent Ga(1)O6 octahedra,  a cornercorner with one B(1)O4 tetrahedra, and corners with two equivalent B(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 54-62°. In the second B site, B(2) is bonded to two equivalent O(1) and two equivalent O(4) atoms to form BO4 tetrahedra that share corners with two equivalent Ga(1)O6 octahedra, corners with two equivalent Ga(2)O6 octahedra, and corners with four equivalent B(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 62°. There are five inequivalent O sites. In the first O site, O(5) is bonded in a trigonal non-coplanar geometry to one Ga(1) and two equivalent Ga(2) atoms. In the second O site, O(1) is bonded in a trigonal planar geometry to one Ga(2), one B(1), and one B(2) atom. In the third O site, O(2) is bonded in a distorted trigonal planar geometry to one Ga(1), one Ga(2), and one B(1) atom. In the fourth O site, O(3) is bonded in a trigonal planar geometry to one Ga(1) and two equivalent B(1) atoms. In the fifth O site, O(4) is bonded in a trigonal planar geometry to one Ga(1), one B(1), and one B(2) atom. is represented by the CIF card [CIF]
