The crystal structure described by Li2V2GeSiO10 crystallizes in the orthorhombic Pccm 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 57°. V(1) is bonded to one O(1), two equivalent O(2), 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(2) 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. The corner-sharing octahedral tilt angles are 60°. Si(1) is bonded to four equivalent O(3) atoms to form SiO4 tetrahedra that share corners with four equivalent Li(1)O6 octahedra and corners with four equivalent V(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 61°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Li(1) and one V(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Li(1), one V(1), and one Ge(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Li(1), one V(1), and one Si(1) atom. is represented by the CIF card [CIF]
