The material structure described by Nd3Cd2Si3O13 crystallizes in the hexagonal P6_3/m space group. Nd(1) is bonded in a 7-coordinate geometry to one O(1), one O(2), one O(3), and four equivalent O(4) atoms. Cd(1) is bonded in a 6-coordinate geometry to three equivalent O(1) and three equivalent O(3) atoms. Si(1) is bonded in a tetrahedral geometry to one O(1), one O(3), and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Nd(1), two equivalent Cd(1), and one Si(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to three equivalent Nd(1) atoms. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Nd(1), two equivalent Cd(1), and one Si(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to two equivalent Nd(1) and one Si(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
