Materials Data on Zr2(CuSb)3 by Materials Project
Zr2(CuSb)3 crystallizes in the tetragonal P4mm space group. The structure is two-dimensional and consists of one Zr2(CuSb)3 sheet oriented in the (0, 0, 1) direction. there are two inequivalent Zr3+ sites. In the first Zr3+ site, Zr3+ is bonded in a 8-coordinate geometry to eight Sb3- atoms. There are four shorter (3.09 Å) and four longer (3.20 Å) Zr–Sb bond lengths. In the second Zr3+ site, Zr3+ is bonded in a 4-coordinate geometry to four equivalent Sb3- atoms. All Zr–Sb bond lengths are 3.04 Å. There are two inequivalent Cu1+ sites. In the first Cu1+ site, Cu1+ is bonded to two equivalent Cu1+ and two equivalent Sb3- atoms to form a mixture of corner and edge-sharing CuCu2Sb2 tetrahedra. Both Cu–Cu bond lengths are 2.48 Å. Both Cu–Sb bond lengths are 2.64 Å. In the second Cu1+ site, Cu1+ is bonded in a 4-coordinate geometry to four equivalent Cu1+ atoms. There are two inequivalent Sb3- sites. In the first Sb3- site, Sb3- is bonded in a 8-coordinate geometry to four Zr3+ atoms. In the second Sb3- site, Sb3- is bonded in a 8-coordinate geometry to four equivalent Zr3+ and four equivalent Cu1+ atoms.
