Gd3Si is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Gd(1) is bonded in a 4-coordinate geometry to four equivalent Si(1) atoms. Si(1) is bonded to twelve equivalent Gd(1) atoms to form a mixture of corner and face-sharing SiGd12 cuboctahedra.
Gd3Si is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Gd(1) is bonded in a 4-coordinate geometry to four equivalent Si(1) atoms. There are two shorter (3.17 Å) and two longer (3.37 Å) Gd(1)-Si(1) bond lengths. Si(1) is bonded to twelve equivalent Gd(1) atoms to form a mixture of corner and face-sharing SiGd12 cuboctahedra.
