Materials Data on Er(CoGe)6 by Materials Project
Er(CoGe)6 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Er is bonded to twelve equivalent Co and eight Ge atoms to form distorted ErCo12Ge8 hexagonal bipyramids that share faces with twenty-four equivalent CoEr2Co4Ge6 cuboctahedra and faces with six equivalent ErCo12Ge8 hexagonal bipyramids. All Er–Co bond lengths are 3.21 Å. There are two shorter (2.70 Å) and six longer (2.93 Å) Er–Ge bond lengths. Co is bonded to two equivalent Er, four equivalent Co, and six Ge atoms to form distorted CoEr2Co4Ge6 cuboctahedra that share corners with fourteen equivalent CoEr2Co4Ge6 cuboctahedra, edges with seven equivalent CoEr2Co4Ge6 cuboctahedra, faces with nine equivalent CoEr2Co4Ge6 cuboctahedra, and faces with four equivalent ErCo12Ge8 hexagonal bipyramids. All Co–Co bond lengths are 2.53 Å. There are four shorter (2.45 Å) and two longer (2.64 Å) Co–Ge bond lengths. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 12-coordinate geometry to three equivalent Er and six equivalent Co atoms. In the second Ge site, Ge is bonded in a 6-coordinate geometry to six equivalent Co atoms. In the third Ge site, Ge is bonded in a 8-coordinate geometry to one Er, six equivalent Co, and one Ge atom. The Ge–Ge bond length is 2.44 Å.
