Materials Data on La5CoGe3 by Materials Project
La5CoGe3 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent La sites. In the first La site, La is bonded in a 5-coordinate geometry to two equivalent Co and three equivalent Ge atoms. Both La–Co bond lengths are 2.80 Å. There are one shorter (3.19 Å) and two longer (3.22 Å) La–Ge bond lengths. In the second La site, La is bonded in a 6-coordinate geometry to six equivalent Ge atoms. All La–Ge bond lengths are 3.27 Å. Co is bonded to six equivalent La atoms to form face-sharing CoLa6 octahedra. Ge is bonded in a 7-coordinate geometry to seven La atoms.
