The structure described by NdCo9Ga4 crystallizes in the tetragonal I4/mcm space group. Nd(1) is bonded in a 24-coordinate geometry to eight equivalent Co(1), eight equivalent Co(2), and eight equivalent Ga(1) atoms. There are three inequivalent Co sites. In the first Co site, Co(3) is bonded in a cuboctahedral geometry to four equivalent Co(1), four equivalent Co(2), and four equivalent Ga(1) atoms. In the second Co site, Co(1) is bonded in a 12-coordinate geometry to two equivalent Nd(1), one Co(3), two equivalent Co(2), three equivalent Co(1), and four equivalent Ga(1) atoms. In the third Co site, Co(2) is bonded in a 12-coordinate geometry to two equivalent Nd(1), one Co(3), two equivalent Co(1), three equivalent Co(2), and four equivalent Ga(1) atoms. Ga(1) is bonded in a 11-coordinate geometry to two equivalent Nd(1), one Co(3), four equivalent Co(1), and four equivalent Co(2) atoms. is represented by the CIF file [CIF]
