The material structure described by BaSn5 crystallizes in the hexagonal P6/mmm space group. Ba(1) is bonded in a 14-coordinate geometry to two equivalent Sn(2) and twelve equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 7-coordinate geometry to three equivalent Ba(1) and four equivalent Sn(1) atoms. In the second Sn site, Sn(2) is bonded in a linear geometry to two equivalent Ba(1) atoms. is represented by the CIF card [CIF]
