Materials Data on KEu(CuTe2)2 by Materials Project
Abstract
KEu(CuTe2)2 crystallizes in the tetragonal P4mm space group. The structure is three-dimensional. K1+ is bonded in a 8-coordinate geometry to eight Te2- atoms. There are four shorter (3.53 Å) and four longer (3.72 Å) K–Te bond lengths. Eu3+ is bonded in a 8-coordinate geometry to eight Te2- atoms. There are four shorter (3.33 Å) and four longer (3.39 Å) Eu–Te bond lengths. Cu2+ is bonded to four Te2- atoms to form a mixture of corner and edge-sharing CuTe4 tetrahedra. There are two shorter (2.65 Å) and two longer (2.77 Å) Cu–Te bond lengths. There are three inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 8-coordinate geometry to four equivalent K1+ and four equivalent Cu2+ atoms. In the second Te2- site, Te2- is bonded in a 8-coordinate geometry to two equivalent K1+, two equivalent Eu3+, and four equivalent Te2- atoms. All Te–Te bond lengths are 3.14 Å. In the third Te2- site, Te2- is bonded in a 8-coordinate geometry to four equivalent Eu3+ and four equivalent Cu2+ atoms.
