The material structure described by Tb3Co3Ga crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 9-coordinate geometry to two equivalent Co(2), four equivalent Co(1), and three equivalent Ga(1) atoms. In the second Tb site, Tb(2) is bonded in a 9-coordinate geometry to three equivalent Co(2), four equivalent Co(1), and two equivalent Ga(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to two equivalent Tb(2), four equivalent Tb(1), one Co(2), and two equivalent Ga(1) atoms. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to three equivalent Tb(2), four equivalent Tb(1), and two equivalent Co(1) atoms. Ga(1) is bonded to two equivalent Tb(2), six equivalent Tb(1), and four equivalent Co(1) atoms to form a mixture of edge, corner, and face-sharing GaTb8Co4 cuboctahedra. is represented by the CIF file [CIF]
