The crystal structure described by Ba4Zn11Ge12 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 8-coordinate geometry to eight equivalent Ge(1) atoms. In the second Ba site, Ba(2) is bonded in a 20-coordinate geometry to eight equivalent Zn(2) and twelve equivalent Ge(1) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a tetrahedral geometry to four equivalent Ge(1) atoms. In the second Zn site, Zn(2) is bonded in a 3-coordinate geometry to one Ba(2) and three equivalent Ge(1) atoms. Ge(1) is bonded in a 3-coordinate geometry to one Ba(2), two equivalent Ba(1), one Zn(1), and two equivalent Zn(2) atoms. is represented by the CIF file [CIF]
