Local coordination around the Ba atoms in the structure. Each Ba atom is bonded to two neighboring Ba atoms and 17 Cu atoms with an average bond distance of 3.398 Å. The Ba—Ba distance is 3.8366 (5) Å, which is slightly longer than the Ba—Ba distance in BaZn5 and slightly shorter than the Sr—Sr distance in SrZn5.
