BaZn5 crystallizes in the orthorhombic Cmcm space group. Ba(1) is bonded in a 21-coordinate geometry to two equivalent Ba(1), three equivalent Zn(2), eight equivalent Zn(1), and eight equivalent Zn(3) atoms. There are three inequivalent Zn sites. In the first Zn site, Zn(3) is bonded in a 11-coordinate geometry to four equivalent Ba(1), one Zn(2), two equivalent Zn(3), and four equivalent Zn(1) atoms. In the second Zn site, Zn(1) is bonded in a 12-coordinate geometry to four equivalent Ba(1), two equivalent Zn(1), two equivalent Zn(2), and four equivalent Zn(3) atoms. In the third Zn site, Zn(2) is bonded in a 11-coordinate geometry to three equivalent Ba(1), two equivalent Zn(2), two equivalent Zn(3), and four equivalent Zn(1) atoms.
BaZn5 crystallizes in the orthorhombic Cmcm space group. Ba(1) is bonded in a 21-coordinate geometry to two equivalent Ba(1), three equivalent Zn(2), eight equivalent Zn(1), and eight equivalent Zn(3) atoms. Both Ba(1)-Ba(1) bond lengths are 3.80 Å. There are two shorter (3.40 Å) and one longer (3.44 Å) Ba(1)-Zn(2) bond length. There are four shorter (3.74 Å) and four longer (3.78 Å) Ba(1)-Zn(1) bond lengths. There are six shorter (3.42 Å) and two longer (3.86 Å) Ba(1)-Zn(3) bond lengths. There are three inequivalent Zn sites.
