The structure described by Tb5Ga3 crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 6-coordinate geometry to two equivalent Ga(1) and four equivalent Ga(2) atoms. In the second Tb site, Tb(2) is bonded to two equivalent Ga(1) and three equivalent Ga(2) atoms to form a mixture of distorted edge, face, and corner-sharing TbGa5 trigonal bipyramids. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to two equivalent Tb(1) and eight equivalent Tb(2) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to two equivalent Tb(1), six equivalent Tb(2), and one Ga(2) atom. is represented by the CIF card [CIF]
