Abstract

Eu(MgGe)3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are three inequivalent Mg sites. In the first Mg site, Mg is bonded to four Ge atoms to form a mixture of corner and edge-sharing MgGe4 tetrahedra. There are two shorter (2.73 Å) and two longer (2.80 Å) Mg–Ge bond lengths. In the second Mg site, Mg is bonded to four Ge atoms to form a mixture of corner and edge-sharing MgGe4 tetrahedra. There are two shorter (2.76 Å) and two longer (2.78 Å) Mg–Ge bond lengths. In the third Mg site, Mg is bonded to four equivalent Ge atoms to form a mixture of corner and edge-sharing MgGe4 tetrahedra. There are two shorter (2.74 Å) and two longer (2.80 Å) Mg–Ge bond lengths. Eu is bonded in a 2-coordinate geometry to ten Ge atoms. There are a spread of Eu–Ge bond distances ranging from 3.17–3.46 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to six equivalent Eu and three Ge atoms. There are one shorter (2.50 Å) and two longer (2.52 Å) Ge–Ge bond lengths. In the second Ge site, Ge is bonded in amore »« less
