Zn2SiO4 crystallizes in the tetragonal I-42d space group. Zn(1) is bonded to four equivalent O(1) atoms to form ZnO4 tetrahedra that share corners with four equivalent Zn(1)O4 tetrahedra and corners with four equivalent Si(1)O4 tetrahedra. Si(1) is bonded to four equivalent O(1) atoms to form SiO4 tetrahedra that share corners with eight equivalent Zn(1)O4 tetrahedra. O(1) is bonded in a trigonal planar geometry to two equivalent Zn(1) and one Si(1) atom.
