Nd2Ge(BO4)2 crystallizes in the orthorhombic Pbcn space group. Nd(1) is bonded in a 7-coordinate geometry to one O(2), one O(3), two equivalent O(4), and three equivalent O(1) atoms. B(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form BO4 tetrahedra that share  a cornercorner with one Ge(1)O4 tetrahedra and corners with two equivalent B(1)O4 tetrahedra. Ge(1) is bonded to two equivalent O(2) and two equivalent O(4) atoms to form GeO4 tetrahedra that share corners with two equivalent B(1)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Nd(1) and two equivalent B(1) atoms. In the second O site, O(4) is bonded in a trigonal planar geometry to two equivalent Nd(1) and one Ge(1) atom. In the third O site, O(1) is bonded in a distorted single-bond geometry to three equivalent Nd(1) and one B(1) atom. In the fourth O site, O(2) is bonded in a 3-coordinate geometry to one Nd(1), one B(1), and one Ge(1) atom.
