The compound described by Sm9Ga4 crystallizes in the tetragonal I4/m space group. There are three inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a square co-planar geometry to four equivalent Ga(1) atoms. In the second Sm site, Sm(2) is bonded in a 4-coordinate geometry to four equivalent Ga(1) atoms. In the third Sm site, Sm(3) is bonded in a 3-coordinate geometry to five equivalent Ga(1) atoms. Ga(1) is bonded in a 10-coordinate geometry to one Sm(1), four equivalent Sm(2), and five equivalent Sm(3) atoms. is represented by the CIF card [CIF]
