The material structure described by Ba4Ag3Ge20 crystallizes in the cubic Pm-3n space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 12-coordinate geometry to four equivalent Ag(1) and eight equivalent Ge(1) atoms. In the second Ba site, Ba(2) is bonded in a 20-coordinate geometry to eight equivalent Ge(2) and twelve equivalent Ge(1) atoms. Ag(1) is bonded to four equivalent Ba(1) and four equivalent Ge(1) atoms to form a mixture of distorted edge and corner-sharing AgBa4Ge4 tetrahedra. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 7-coordinate geometry to one Ba(2), two equivalent Ba(1), one Ag(1), one Ge(1), and two equivalent Ge(2) atoms. In the second Ge site, Ge(2) is bonded in a 5-coordinate geometry to one Ba(2), one Ge(2), and three equivalent Ge(1) atoms. is represented by the CIF file [CIF]
