Materials Data on Zr9(CoP2)2 by Materials Project
Zr9(CoP2)2 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. there are four inequivalent Zr sites. In the first Zr site, Zr is bonded in a distorted hexagonal planar geometry to two equivalent Co and four equivalent P atoms. Both Zr–Co bond lengths are 2.68 Å. There are two shorter (2.74 Å) and two longer (2.78 Å) Zr–P bond lengths. In the second Zr site, Zr is bonded in a 6-coordinate geometry to two equivalent Co and four equivalent P atoms. Both Zr–Co bond lengths are 2.86 Å. All Zr–P bond lengths are 2.73 Å. In the third Zr site, Zr is bonded in a square co-planar geometry to four equivalent P atoms. All Zr–P bond lengths are 2.81 Å. In the fourth Zr site, Zr is bonded in a T-shaped geometry to one Co and two equivalent P atoms. The Zr–Co bond length is 2.65 Å. Both Zr–P bond lengths are 2.86 Å. Co is bonded in a 9-coordinate geometry to seven Zr and two equivalent P atoms. Both Co–P bond lengths are 2.35 Å. P is bonded in a 9-coordinate geometry to eight Zr and one Co atom.
