The material structure described by ZnSiO3 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a rectangular see-saw-like geometry to one O(1), one O(3), one O(4), and one O(6) atom. In the second Zn site, Zn(2) is bonded to one O(4), one O(6), two equivalent O(1), and two equivalent O(3) atoms to form ZnO6 octahedra that share corners with three equivalent Si(1)O4 tetrahedra, corners with three equivalent Si(2)O4 tetrahedra, and edges with two equivalent Zn(2)O6 octahedra. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded to one O(1), one O(4), and two equivalent O(5) atoms to form SiO4 tetrahedra that share corners with three equivalent Zn(2)O6 octahedra and corners with two equivalent Si(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 33-62°. In the second Si site, Si(2) is bonded to one O(3), one O(6), and two equivalent O(2) atoms to form SiO4 tetrahedra that share corners with three equivalent Zn(2)O6 octahedra and corners with two equivalent Si(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 46-62°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Zn(1), two equivalent Zn(2), and one Si(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to two equivalent Si(2) atoms. In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to one Zn(1), two equivalent Zn(2), and one Si(2) atom. In the fourth O site, O(4) is bonded in a distorted T-shaped geometry to one Zn(1), one Zn(2), and one Si(1) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to two equivalent Si(1) atoms. In the sixth O site, O(6) is bonded in a distorted trigonal planar geometry to one Zn(1), one Zn(2), and one Si(2) atom. is represented by the CIF file [CIF]
