The crystal structure described by Ba5Ge3 crystallizes in the tetragonal P4/ncc space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 5-coordinate geometry to two equivalent Ge(2) and three equivalent Ge(1) atoms. In the second Ba site, Ba(2) is bonded to one Ge(2) and four equivalent Ge(1) atoms to form distorted corner-sharing BaGe5 square pyramids. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Ba(2), six equivalent Ba(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to one Ba(2) and eight equivalent Ba(1) atoms. is represented by the CIF file [CIF]
