Materials Data on EuZnGe by Materials Project

Abstract

EuZnGe crystallizes in the orthorhombic Pmmm space group. The structure is three-dimensional. there are two inequivalent Eu sites. In the first Eu site, Eu is bonded to four equivalent Zn and eight equivalent Ge atoms to form a mixture of edge and face-sharing EuZn4Ge8 cuboctahedra. All Eu–Zn bond lengths are 3.31 Å. All Eu–Ge bond lengths are 3.31 Å. In the second Eu site, Eu is bonded to eight equivalent Zn and four equivalent Ge atoms to form a mixture of edge and face-sharing EuZn8Ge4 cuboctahedra. All Eu–Zn bond lengths are 3.31 Å. All Eu–Ge bond lengths are 3.30 Å. Zn is bonded in a 2-coordinate geometry to six Eu, one Zn, and two equivalent Ge atoms. The Zn–Zn bond length is 2.50 Å. Both Zn–Ge bond lengths are 2.49 Å. Ge is bonded in a distorted bent 120 degrees geometry to six Eu, two equivalent Zn, and one Ge atom. The Ge–Ge bond length is 2.52 Å.
