Materials Data on K3Co by Materials Project

K3Co crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. K is bonded in a 12-coordinate geometry to eight equivalent K and four equivalent Co atoms. There are a spread of K–K bond distances ranging from 3.76–4.35 Å. There are two shorter (3.83 Å) and two longer (4.06 Å) K–Co bond lengths. Co is bonded to twelve equivalent K atoms to form a mixture of corner and face-sharing CoK12 cuboctahedra.
