The structure described by K4In3Ge20 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 12-coordinate geometry to four equivalent In(1) and eight equivalent Ge(2) atoms. In the second K site, K(2) is bonded in a 20-coordinate geometry to eight equivalent Ge(1) and twelve equivalent Ge(2) atoms. In(1) is bonded to four equivalent K(1) and four equivalent Ge(2) atoms to form a mixture of corner and edge-sharing InK4Ge4 tetrahedra. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 5-coordinate geometry to one K(2), one Ge(1), and three equivalent Ge(2) atoms. In the second Ge site, Ge(2) is bonded in a 7-coordinate geometry to one K(2), two equivalent K(1), one In(1), one Ge(2), and two equivalent Ge(1) atoms. is represented by the CIF card [CIF]
