NaScGe2O6 is Esseneite structured and crystallizes in the monoclinic C2/c space group. Na(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Sc(1) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form ScO6 octahedra that share corners with six equivalent Ge(1)O4 tetrahedra and edges with two equivalent Sc(1)O6 octahedra. Ge(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form GeO4 tetrahedra that share corners with three equivalent Sc(1)O6 octahedra and corners with two equivalent Ge(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 35-60°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Na(1) and two equivalent Ge(1) atoms. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Na(1), one Sc(1), and one Ge(1) atom. In the third O site, O(3) is bonded to one Na(1), two equivalent Sc(1), and one Ge(1) atom to form a mixture of distorted edge and corner-sharing ONaSc2Ge tetrahedra.
NaScGe2O6 is Esseneite structured and crystallizes in the monoclinic C2/c space group. Na(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Both Na(1)-O(1) bond lengths are 2.48 Å. Both Na(1)-O(2) bond lengths are 2.57 Å. Both Na(1)-O(3) bond lengths are 2.52 Å. Sc(1) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form ScO6 octahedra that share corners with six equivalent Ge(1)O4 tetrahedra and edges with two equivalent Sc(1)O6 octahedra. Both Sc(1)-O(2) bond lengths are 2.03 Å. There are two shorter (2.15 Å) and two longer (2.23 Å) Sc(1)-O(3) bond lengths. Ge(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form GeO4 tetrahedra that share corners with three equivalent Sc(1)O6 octahedra and corners with two equivalent Ge(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 35-60°. The Ge(1)-O(2) bond length is 1.74 Å. The Ge(1)-O(3) bond length is 1.77 Å. There is one shorter (1.79 Å) and one longer (1.80 Å) Ge(1)-O(1) bond length. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Na(1) and two equivalent Ge(1) atoms. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Na(1), one Sc(1), and one Ge(1) atom. In the third O site, O(3) is bonded to one Na(1), two equivalent Sc(1), and one Ge(1) atom to form a mixture of distorted edge and corner-sharing ONaSc2Ge tetrahedra.
