The material structure described by Nd3Ga2 crystallizes in the tetragonal I4/mcm space group. There are three inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 4-coordinate geometry to two equivalent Ga(3) and four equivalent Ga(4) atoms. In the second Nd site, Nd(2) is bonded in a 5-coordinate geometry to two equivalent Ga(4) and three equivalent Ga(3) atoms. In the third Nd site, Nd(3) is bonded in a 6-coordinate geometry to one Ga(1), one Ga(2), one Ga(3), and three equivalent Ga(4) atoms. There are four inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 8-coordinate geometry to eight equivalent Nd(3) atoms. In the second Ga site, Ga(2) is bonded in a body-centered cubic geometry to eight equivalent Nd(3) atoms. In the third Ga site, Ga(3) is bonded in a 9-coordinate geometry to two equivalent Nd(1), three equivalent Nd(2), and four equivalent Nd(3) atoms. In the fourth Ga site, Ga(4) is bonded in a 10-coordinate geometry to one Nd(2), two equivalent Nd(1), six equivalent Nd(3), and one Ga(4) atom. is represented by the Crystallographic Information File (CIF) [CIF]
