ZrCo4Si crystallizes in the cubic F-43m space group. Zr(1) is bonded in a 16-coordinate geometry to twelve equivalent Co(1) and four equivalent Si(1) atoms. Co(1) is bonded to three equivalent Zr(1), six equivalent Co(1), and three equivalent Si(1) atoms to form a mixture of corner, edge, and face-sharing CoZr3Co6Si3 cuboctahedra. Si(1) is bonded in a 16-coordinate geometry to four equivalent Zr(1) and twelve equivalent Co(1) atoms.
ZrCo4Si crystallizes in the cubic F-43m space group. Zr(1) is bonded in a 16-coordinate geometry to twelve equivalent Co(1) and four equivalent Si(1) atoms. All Zr(1)-Co(1) bond lengths are 2.78 Å. All Zr(1)-Si(1) bond lengths are 2.90 Å. Co(1) is bonded to three equivalent Zr(1), six equivalent Co(1), and three equivalent Si(1) atoms to form a mixture of corner, edge, and face-sharing CoZr3Co6Si3 cuboctahedra. There are three shorter (2.34 Å) and three longer (2.40 Å) Co(1)-Co(1) bond lengths. All Co(1)-Si(1) bond lengths are 2.78 Å. Si(1) is bonded in a 16-coordinate geometry to four equivalent Zr(1) and twelve equivalent Co(1) atoms.
