K3Co is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 4-coordinate geometry to four equivalent K(2) and four equivalent Co(1) atoms. In the second K site, K(2) is bonded to eight equivalent K(1) and four equivalent Co(1) atoms to form a mixture of distorted edge, face, and corner-sharing KK8Co4 cuboctahedra. Co(1) is bonded in a distorted body-centered cubic geometry to four equivalent K(2) and eight equivalent K(1) atoms.
