The compound described by Li2CuSiO4 is Stannite structured and crystallizes in the tetragonal I-42m space group. Li(1) is bonded to four equivalent O(1) atoms to form LiO4 tetrahedra that share corners with four equivalent Li(1)O4 tetrahedra, corners with four equivalent Cu(1)O4 tetrahedra, and corners with four equivalent Si(1)O4 tetrahedra. Cu(1) is bonded to four equivalent O(1) atoms to form distorted CuO4 tetrahedra that share corners with four equivalent Si(1)O4 tetrahedra and corners with eight equivalent Li(1)O4 tetrahedra. Si(1) is bonded to four equivalent O(1) atoms to form SiO4 tetrahedra that share corners with four equivalent Cu(1)O4 tetrahedra and corners with eight equivalent Li(1)O4 tetrahedra. O(1) is bonded to two equivalent Li(1), one Cu(1), and one Si(1) atom to form corner-sharing OLi2CuSi tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
