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.

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. Both Cd(1)-O(2) bond lengths are 2.31 Å. There are two shorter (2.25 Å) and two longer (2.41 Å) Cd(1)-O(1) bond lengths. 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. Both Cd(2)-O(1) bond lengths are 2.37 Å. Both Cd(2)-O(2) bond lengths are 2.18 Å. Both Cd(2)-O(3) bond lengths are 2.67 Å. 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°. The Si(1)-O(1) bond length is 1.63 Å. The Si(1)-O(2) bond length is 1.62 Å. There is one shorter (1.67 Å) and one longer (1.69 Å) Si(1)-O(3) bond length. 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.
