The structure described by K4Ge23 crystallizes in the cubic Pm-3n space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 20-coordinate geometry to eight equivalent Ge(2) and twelve equivalent Ge(3) atoms. In the second K site, K(2) is bonded in a 12-coordinate geometry to four equivalent Ge(1) and eight equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to four equivalent K(2) and four equivalent Ge(3) atoms to form a mixture of distorted corner and edge-sharing GeK4Ge4 tetrahedra. In the second Ge site, Ge(2) is bonded in a 5-coordinate geometry to one K(1), one Ge(2), and three equivalent Ge(3) atoms. In the third Ge site, Ge(3) is bonded in a 7-coordinate geometry to one K(1), two equivalent K(2), one Ge(1), one Ge(3), and two equivalent Ge(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
