Materials Data on EuGeAu by Materials Project
EuAuGe crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. there are two inequivalent Eu sites. In the first Eu site, Eu is bonded in a 12-coordinate geometry to six equivalent Au and six equivalent Ge atoms. There are two shorter (3.17 Å) and four longer (3.25 Å) Eu–Au bond lengths. There are two shorter (3.26 Å) and four longer (3.44 Å) Eu–Ge bond lengths. In the second Eu site, Eu is bonded in a 12-coordinate geometry to six equivalent Au and six equivalent Ge atoms. There are four shorter (3.29 Å) and two longer (3.36 Å) Eu–Au bond lengths. There are four shorter (3.15 Å) and two longer (3.32 Å) Eu–Ge bond lengths. Au is bonded in a 10-coordinate geometry to six Eu, one Au, and three equivalent Ge atoms. The Au–Au bond length is 3.24 Å. There are two shorter (2.69 Å) and one longer (2.73 Å) Au–Ge bond lengths. Ge is bonded in a 3-coordinate geometry to six Eu, three equivalent Au, and one Ge atom. The Ge–Ge bond length is 2.80 Å.
