The structure described by Y5Ga3 crystallizes in the tetragonal P4/ncc space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded to two equivalent Ga(2) and three equivalent Ga(1) atoms to form a mixture of distorted face, corner, and edge-sharing YGa5 trigonal bipyramids. In the second Y site, Y(2) is bonded in a 4-coordinate geometry to two equivalent Ga(2) and four equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to two equivalent Y(2), six equivalent Y(1), and one Ga(1) atom. In the second Ga site, Ga(2) is bonded in a 10-coordinate geometry to two equivalent Y(2) and eight equivalent Y(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
