The structure described by Nd4CdSi3O13 crystallizes in the hexagonal P6_3 space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 9-coordinate geometry to three equivalent O(1), three equivalent O(2), and three equivalent O(5) atoms. In the second Nd site, Nd(2) is bonded in a 7-coordinate geometry to one O(1), one O(4), one O(5), two equivalent O(2), and two equivalent O(3) atoms. Cd(1) is bonded in a 6-coordinate geometry to three equivalent O(1) and three equivalent O(5) atoms. Si(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(5) atom. There are five inequivalent O sites. In the first O site, O(4) is bonded in a trigonal planar geometry to three equivalent Nd(2) atoms. In the second O site, O(5) is bonded in a 4-coordinate geometry to one Nd(1), one Nd(2), one Cd(1), and one Si(1) atom. In the third O site, O(1) is bonded in a 4-coordinate geometry to one Nd(1), one Nd(2), one Cd(1), and one Si(1) atom. In the fourth O site, O(2) is bonded in a 4-coordinate geometry to one Nd(1), two equivalent Nd(2), and one Si(1) atom. In the fifth O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Nd(2) and one Si(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
