Li2V2GeSiO10 crystallizes in the orthorhombic C222 space group. Li(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted LiO6 octahedra that share corners with two equivalent Li(1)O6 octahedra, corners with two equivalent Ge(1)O4 tetrahedra, corners with two equivalent Si(1)O4 tetrahedra, corners with two equivalent V(1)O5 trigonal bipyramids, and edges with two equivalent V(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 56°. V(1) is bonded to one O(2), two equivalent O(1), and two equivalent O(3) atoms to form distorted VO5 trigonal bipyramids that share corners with two equivalent Li(1)O6 octahedra, corners with two equivalent Ge(1)O4 tetrahedra, corners with two equivalent Si(1)O4 tetrahedra, and edges with two equivalent Li(1)O6 octahedra. The corner-sharing octahedral tilt angles are 62°. Ge(1) is bonded to four equivalent O(3) atoms to form GeO4 tetrahedra that share corners with four equivalent Li(1)O6 octahedra and corners with four equivalent V(1)O5 trigonal bipyramids.
