The compound described by TbCo3Ga2 crystallizes in the hexagonal P-62m space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 18-coordinate geometry to three equivalent Co(2), six equivalent Co(1), three equivalent Ga(2), and six equivalent Ga(1) atoms. In the second Tb site, Tb(2) is bonded in a distorted hexagonal planar geometry to six equivalent Co(1), six equivalent Co(2), and six equivalent Ga(2) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 11-coordinate geometry to one Tb(2), two equivalent Tb(1), two equivalent Co(1), two equivalent Co(2), two equivalent Ga(1), and two equivalent Ga(2) atoms. In the second Co site, Co(2) is bonded to two equivalent Tb(1), two equivalent Tb(2), four equivalent Co(1), two equivalent Ga(1), and two equivalent Ga(2) atoms to form distorted CoTb4Ga4Co4 cuboctahedra that share corners with six equivalent Ga(2)Tb4Ga2Co6 cuboctahedra, corners with eight equivalent Co(2)Tb4Ga4Co4 cuboctahedra, edges with five equivalent Ga(2)Tb4Ga2Co6 cuboctahedra, faces with three equivalent Ga(2)Tb4Ga2Co6 cuboctahedra, and faces with four equivalent Co(2)Tb4Ga4Co4 cuboctahedra. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 12-coordinate geometry to four equivalent Tb(1), two equivalent Co(2), four equivalent Co(1), and two equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded to two equivalent Tb(1), two equivalent Tb(2), two equivalent Co(2), four equivalent Co(1), and two equivalent Ga(1) atoms to form distorted GaTb4Ga2Co6 cuboctahedra that share corners with six equivalent Co(2)Tb4Ga4Co4 cuboctahedra, corners with eight equivalent Ga(2)Tb4Ga2Co6 cuboctahedra, edges with five equivalent Co(2)Tb4Ga4Co4 cuboctahedra, faces with three equivalent Co(2)Tb4Ga4Co4 cuboctahedra, and faces with four equivalent Ga(2)Tb4Ga2Co6 cuboctahedra. is represented by the CIF file [CIF]
