Materials Data on Eu(GaGe2)2 by Materials Project
EuGa2Ge4 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Eu is bonded in a 6-coordinate geometry to four equivalent Ga and ten Ge atoms. All Eu–Ga bond lengths are 3.41 Å. There are a spread of Eu–Ge bond distances ranging from 3.42–3.58 Å. Ga is bonded in a 6-coordinate geometry to two equivalent Eu, two equivalent Ga, and two Ge atoms. Both Ga–Ga bond lengths are 2.47 Å. There are one shorter (2.53 Å) and one longer (2.54 Å) Ga–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 1-coordinate geometry to three equivalent Eu, one Ga, and three Ge atoms. There are one shorter (2.52 Å) and two longer (2.54 Å) Ge–Ge bond lengths. In the second Ge site, Ge is bonded in a 1-coordinate geometry to two equivalent Eu, one Ga, and three Ge atoms. The Ge–Ge bond length is 2.56 Å.
