The structure described by KMg6V crystallizes in the tetragonal P4/mmm space group. K(1) is bonded in a 14-coordinate geometry to two equivalent K(1), four equivalent Mg(1), and eight equivalent Mg(2) atoms. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded to two equivalent K(1), two equivalent Mg(1), and eight equivalent Mg(2) atoms to form a mixture of face and corner-sharing MgK2Mg10 cuboctahedra. In the second Mg site, Mg(2) is bonded in a 2-coordinate geometry to two equivalent K(1), four equivalent Mg(1), and two equivalent V(1) atoms. V(1) is bonded in a body-centered cubic geometry to eight equivalent Mg(2) atoms. is represented by the CIF file [CIF]
