The crystal structure described by Tb(Co2Ga)4 crystallizes in the tetragonal I4/mmm space group. Tb(1) is bonded in a 20-coordinate geometry to eight equivalent Co(1), eight equivalent Co(2), and four equivalent Ga(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a distorted q6 geometry to two equivalent Tb(1), two equivalent Co(1), four equivalent Co(2), and four equivalent Ga(1) atoms. In the second Co site, Co(2) is bonded to two equivalent Tb(1), two equivalent Co(2), four equivalent Co(1), and four equivalent Ga(1) atoms to form a mixture of corner, edge, and face-sharing CoTb2Ga4Co6 cuboctahedra. Ga(1) is bonded in a 10-coordinate geometry to one Tb(1), four equivalent Co(1), four equivalent Co(2), and one Ga(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
