The crystal structure described by ZnSiO3 crystallizes in the orthorhombic Ibam space group. Zn(1) is bonded to two equivalent O(2) and two equivalent O(3) atoms to form distorted ZnO4 tetrahedra that share corners with four equivalent Si(1)O4 tetrahedra and edges with two equivalent Zn(1)O4 tetrahedra. Si(1) is bonded to one O(2), one O(3), and two equivalent O(1) atoms to form SiO4 tetrahedra that share corners with two equivalent Si(1)O4 tetrahedra and corners with four equivalent Zn(1)O4 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent Si(1) atoms. In the second O site, O(2) is bonded in a distorted T-shaped geometry to two equivalent Zn(1) and one Si(1) atom. In the third O site, O(3) is bonded in a distorted T-shaped geometry to two equivalent Zn(1) and one Si(1) atom. is represented by the CIF file [CIF]
