Materials Data on Zr3Co by Materials Project

Zr3Co crystallizes in the orthorhombic Cmcm space group. The structure is one-dimensional and consists of four Zr3Co ribbons oriented in the (1, 0, 0) direction. there are two inequivalent Zr sites. In the first Zr site, Zr is bonded in a 2-coordinate geometry to two equivalent Co atoms. Both Zr–Co bond lengths are 2.64 Å. In the second Zr site, Zr is bonded in a 2-coordinate geometry to two equivalent Co atoms. Both Zr–Co bond lengths are 2.59 Å. Co is bonded in a 6-coordinate geometry to six Zr atoms.

Materials Data on Zr3Co by Materials Project

Zr3Co is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Zr is bonded to eight equivalent Zr and four equivalent Co atoms to form distorted ZrZr8Co4 cuboctahedra that share corners with four equivalent CoZr12 cuboctahedra, corners with fourteen equivalent ZrZr8Co4 cuboctahedra, edges with six equivalent CoZr12 cuboctahedra, edges with twelve equivalent ZrZr8Co4 cuboctahedra, faces with four equivalent CoZr12 cuboctahedra, and faces with sixteen equivalent ZrZr8Co4 cuboctahedra. There are a spread of Zr–Zr bond distances ranging from 2.87–3.19 Å. There are two shorter (2.95 Å) and two longer (3.03 Å) Zr–Co bond lengths. Co is bonded to twelve equivalent Zr atoms to form CoZr12 cuboctahedra that share corners with six equivalent CoZr12 cuboctahedra, corners with twelve equivalent ZrZr8Co4 cuboctahedra, edges with eighteen equivalent ZrZr8Co4 cuboctahedra, faces with eight equivalent CoZr12 cuboctahedra, and faces with twelve equivalent ZrZr8Co4 cuboctahedra.
