SrGe2(BO4)2 crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded in a 7-coordinate geometry to one O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. 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  a cornercorner with one B(1)O4 tetrahedra and corners with three equivalent Ge(1)O4 tetrahedra. Ge(1) is bonded to one O(2), one O(3), one O(4), and one O(5) atom to form GeO4 tetrahedra that share  a cornercorner with one Ge(1)O4 tetrahedra and corners with three equivalent B(1)O4 tetrahedra. There are five inequivalent O sites. In the first O site, O(3) is bonded in a 2-coordinate geometry to one Sr(1), one B(1), and one Ge(1) atom. In the second O site, O(4) is bonded in a 3-coordinate geometry to one Sr(1), one B(1), and one Ge(1) atom. In the third O site, O(5) is bonded in a bent 120 degrees geometry to two equivalent Ge(1) atoms. In the fourth O site, O(1) is bonded in a 3-coordinate geometry to one Sr(1) and two equivalent B(1) atoms. In the fifth O site, O(2) is bonded in a 3-coordinate geometry to one Sr(1), one B(1), and one Ge(1) atom.
