CsK3 crystallizes in the hexagonal P6_3/mmc space group. Cs(1) is bonded to twelve equivalent K(1) atoms to form a mixture of face and corner-sharing CsK12 cuboctahedra. K(1) is bonded in a 6-coordinate geometry to four equivalent Cs(1) and two equivalent K(1) atoms.
CsK3 crystallizes in the hexagonal P6_3/mmc space group. Cs(1) is bonded to twelve equivalent K(1) atoms to form a mixture of face and corner-sharing CsK12 cuboctahedra. There are six shorter (4.99 Å) and six longer (5.07 Å) Cs(1)-K(1) bond lengths. K(1) is bonded in a 6-coordinate geometry to four equivalent Cs(1) and two equivalent K(1) atoms. Both K(1)-K(1) bond lengths are 4.81 Å.
