Materials Data on Eu(ZnSn)2 by Materials Project

EuZn2Sn2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Eu is bonded in a 8-coordinate geometry to eight Zn and eight Sn atoms. There are four shorter (3.54 Å) and four longer (3.61 Å) Eu–Zn bond lengths. There are four shorter (3.51 Å) and four longer (3.72 Å) Eu–Sn bond lengths. There are two inequivalent Zn sites.

All Zn–Sn bond lengths are 2.76 Å. In the second Zn site, Zn is bonded in a 9-coordinate geometry to four equivalent Eu and five Sn atoms. There are one shorter (2.60 Å) and four longer (2.80 Å) Zn–Sn bond lengths. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded to four equivalent Eu and four equivalent Zn atoms to form distorted SnEu4Zn4 tetrahedra that share corners with twelve equivalent ZnEu4Sn4 tetrahedra, edges with two equivalent ZnEu4Sn4 tetrahedra, edges with four equivalent SnEu4Zn4 tetrahedra, and faces with four equivalent SnEu4Zn4 tetrahedra. In the second Sn site, Sn is bonded in a 9-coordinate geometry to four equivalent Eu and five Zn atoms.
