LiCrGe2O6 is Esseneite structured and crystallizes in the monoclinic C2/c space group. Li(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Cr(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CrO6 octahedra that share corners with six equivalent Ge(1)O4 tetrahedra and edges with two equivalent Cr(1)O6 octahedra. Ge(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form GeO4 tetrahedra that share corners with three equivalent Cr(1)O6 octahedra and corners with two equivalent Ge(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 35-65°. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Li(1), two equivalent Cr(1), and one Ge(1) atom to form a mixture of corner and edge-sharing OLiCr2Ge tetrahedra. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Li(1), one Cr(1), and one Ge(1) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to one Li(1) and two equivalent Ge(1) atoms.
LiCrGe2O6 is Esseneite structured and crystallizes in the monoclinic C2/c space group. Li(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Both Li(1)-O(1) bond lengths are 2.09 Å. Both Li(1)-O(2) bond lengths are 2.48 Å. Both Li(1)-O(3) bond lengths are 2.15 Å. Cr(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CrO6 octahedra that share corners with six equivalent Ge(1)O4 tetrahedra and edges with two equivalent Cr(1)O6 octahedra. Both Cr(1)-O(2) bond lengths are 1.91 Å. There are two shorter (2.02 Å) and two longer (2.04 Å) Cr(1)-O(1) bond lengths. Ge(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form GeO4 tetrahedra that share corners with three equivalent Cr(1)O6 octahedra and corners with two equivalent Ge(1)O4 tetrahedra.
