Abstract

Eu(CuSb)2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Eu3+ is bonded in a 8-coordinate geometry to eight Sb3- atoms. There are four shorter (3.41 Å) and four longer (3.64 Å) Eu–Sb bond lengths. There are two inequivalent Cu+1.50+ sites. In the first Cu+1.50+ site, Cu+1.50+ is bonded to four equivalent Sb3- atoms to form a mixture of edge and corner-sharing CuSb4 tetrahedra. All Cu–Sb bond lengths are 2.67 Å. In the second Cu+1.50+ site, Cu+1.50+ is bonded in a 5-coordinate geometry to five Sb3- atoms. There are one shorter (2.53 Å) and four longer (2.72 Å) Cu–Sb bond lengths. There are two inequivalent Sb3- sites. In the first Sb3- site, Sb3- is bonded to four equivalent Eu3+ and four equivalent Cu+1.50+ atoms to form a mixture of distorted edge and face-sharing SbEu4Cu4 tetrahedra. In the second Sb3- site, Sb3- is bonded in a 9-coordinate geometry to four equivalent Eu3+ and five Cu+1.50+ atoms.
