Nd5Ga3 crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 6-coordinate geometry to two equivalent Ga(1) and four equivalent Ga(2) atoms. In the second Nd site, Nd(2) is bonded to two equivalent Ga(1) and three equivalent Ga(2) atoms to form a mixture of distorted face, corner, and edge-sharing NdGa5 trigonal bipyramids. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to two equivalent Nd(1) and eight equivalent Nd(2) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to two equivalent Nd(1), six equivalent Nd(2), and one Ga(2) atom.
