The material structure described by Na3Nd9O3(BO3)8 crystallizes in the hexagonal P-62m space group. Na(1) is bonded in a distorted hexagonal planar geometry to two equivalent O(4) and four equivalent O(2) atoms. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 9-coordinate geometry to one O(3), two equivalent O(2), two equivalent O(4), and four equivalent O(1) atoms. In the second Nd site, Nd(2) is bonded in a 8-coordinate geometry to two equivalent O(3), two equivalent O(4), and four equivalent O(1) atoms. There are three inequivalent B sites. In the first B site, B(1) is bonded in a trigonal planar geometry to three equivalent O(4) atoms. In the second B site, B(2) is bonded in a trigonal planar geometry to three equivalent O(2) atoms. In the third B site, B(3) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. There are four inequivalent O sites. In the first O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Na(1), two equivalent Nd(1), and one B(2) atom. In the second O site, O(3) is bonded to two equivalent Nd(1) and two equivalent Nd(2) atoms to form distorted corner-sharing ONd4 trigonal pyramids. In the third O site, O(4) is bonded in a 5-coordinate geometry to one Na(1), one Nd(2), two equivalent Nd(1), and one B(1) atom. In the fourth O site, O(1) is bonded in a distorted single-bond geometry to one Nd(2), two equivalent Nd(1), and one B(3) atom. is represented by the CIF card [CIF]
