The material described by Nd9Ga4 crystallizes in the tetragonal I4/m space group. There are three inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 4-coordinate geometry to four equivalent Ga(1) atoms. In the second Nd site, Nd(2) is bonded in a square co-planar geometry to four equivalent Ga(1) atoms. In the third Nd site, Nd(3) is bonded in a 3-coordinate geometry to five equivalent Ga(1) atoms. Ga(1) is bonded in a 10-coordinate geometry to one Nd(2), four equivalent Nd(1), and five equivalent Nd(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
