The structure described by CaZnSiO5 crystallizes in the monoclinic Cc space group. Ca(1) is bonded in a 7-coordinate geometry to one O(2), one O(3), one O(4), two equivalent O(1), and two equivalent O(5) atoms. Zn(1) is bonded to one O(2), one O(4), and two equivalent O(3) atoms to form ZnO4 tetrahedra that share corners with two equivalent Zn(1)O4 tetrahedra and corners with four equivalent Si(1)O4 tetrahedra. Si(1) is bonded to one O(2), one O(3), one O(4), and one O(5) atom to form SiO4 tetrahedra that share corners with four equivalent Zn(1)O4 tetrahedra. There are five inequivalent O sites. In the first O site, O(1) is bonded in an L-shaped geometry to two equivalent Ca(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Ca(1), one Zn(1), and one Si(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Ca(1), two equivalent Zn(1), and one Si(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Ca(1), one Zn(1), and one Si(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Ca(1) and one Si(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
