The material described by CdSiO3 is Esseneite-derived structured and crystallizes in the orthorhombic Pbcn space group. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CdO6 octahedra that share corners with six equivalent Si(1)O4 tetrahedra and edges with two equivalent Cd(1)O6 octahedra. In the second Cd site, Cd(2) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Si(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form SiO4 tetrahedra that share corners with three equivalent Cd(1)O6 octahedra and corners with two equivalent Si(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 30-61°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Cd(2), two equivalent Cd(1), and one Si(1) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Cd(1), one Cd(2), and one Si(1) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Cd(2) and two equivalent Si(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
