The structure described by NdGaSi is hexagonal omega structure-derived structured and crystallizes in the tetragonal I4_1md space group. Nd(1) is bonded to six Ga(1,1) and six Si(1,1) atoms to form a mixture of face and edge-sharing NdGa6Si6 cuboctahedra. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to six equivalent Nd(1) and three Si(1,1) atoms. In the second Ga site, Ga(1) is bonded in a 9-coordinate geometry to six equivalent Nd(1) and three Si(1,1) atoms. There are three inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to six equivalent Nd(1) and three Ga(1,1) atoms. In the second Si site, Si(1) is bonded in a 9-coordinate geometry to six equivalent Nd(1) and three Ga(1,1) atoms. In the third Si site, Si(1) is bonded in a 9-coordinate geometry to six equivalent Nd(1) and three equivalent Ga(1) atoms. is represented by the CIF file [CIF]
