Materials Data on EuZnGe by Materials Project

Abstract

EuZnGe crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Eu is bonded to six equivalent Zn and six equivalent Ge atoms to form a mixture of face and edge-sharing EuZn6Ge6 cuboctahedra. There are two shorter (3.32 Å) and four longer (3.33 Å) Eu–Zn bond lengths. All Eu–Ge bond lengths are 3.32 Å. Zn is bonded in a 2-coordinate geometry to six equivalent Eu, one Zn, and two equivalent Ge atoms. The Zn–Zn bond length is 2.53 Å. Both Zn–Ge bond lengths are 2.51 Å. Ge is bonded in a distorted bent 120 degrees geometry to six equivalent Eu, two equivalent Zn, and one Ge atom. The Ge–Ge bond length is 2.54 Å.
