Nd3Si crystallizes in the hexagonal P6_3/mmc space group. Nd(1) is bonded in a 4-coordinate geometry to four equivalent Si(1) atoms. Si(1) is bonded to twelve equivalent Nd(1) atoms to form a mixture of face and corner-sharing SiNd12 cuboctahedra.
Nd3Si crystallizes in the hexagonal P6_3/mmc space group. Nd(1) is bonded in a 4-coordinate geometry to four equivalent Si(1) atoms. There are two shorter (3.17 Å) and two longer (3.53 Å) Nd(1)-Si(1) bond lengths. Si(1) is bonded to twelve equivalent Nd(1) atoms to form a mixture of face and corner-sharing SiNd12 cuboctahedra.
