The crystal structure described by Gd4Co3 crystallizes in the triclinic P-1 space group. There are six inequivalent Gd sites. In the first Gd site, Gd(1) is bonded in a 7-coordinate geometry to two equivalent Co(2), two equivalent Co(4), and three equivalent Co(3) atoms. In the second Gd site, Gd(2) is bonded in a 7-coordinate geometry to two equivalent Co(3), two equivalent Co(4), and three equivalent Co(1) atoms. In the third Gd site, Gd(3) is bonded in a 7-coordinate geometry to two equivalent Co(1), two equivalent Co(4), and three equivalent Co(2) atoms. In the fourth Gd site, Gd(4) is bonded to one Co(3), one Co(5), and two equivalent Co(1) atoms to form a mixture of distorted corner and edge-sharing GdCo4 tetrahedra. In the fifth Gd site, Gd(5) is bonded to one Co(1), one Co(5), and two equivalent Co(2) atoms to form a mixture of distorted corner and edge-sharing GdCo4 tetrahedra. In the sixth Gd site, Gd(6) is bonded to one Co(2), one Co(5), and two equivalent Co(3) atoms to form a mixture of distorted corner and edge-sharing GdCo4 tetrahedra. There are five inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to one Gd(5), two equivalent Gd(3), two equivalent Gd(4), three equivalent Gd(2), and one Co(4) atom. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to one Gd(6), two equivalent Gd(1), two equivalent Gd(5), three equivalent Gd(3), and one Co(4) atom. In the third Co site, Co(3) is bonded in a 9-coordinate geometry to one Gd(4), two equivalent Gd(2), two equivalent Gd(6), three equivalent Gd(1), and one Co(4) atom. In the fourth Co site, Co(4) is bonded in a 9-coordinate geometry to two equivalent Gd(1), two equivalent Gd(2), two equivalent Gd(3), one Co(1), one Co(2), and one Co(3) atom. In the fifth Co site, Co(5) is bonded in a 6-coordinate geometry to two equivalent Gd(4), two equivalent Gd(5), and two equivalent Gd(6) atoms. is represented by the CIF file [CIF]
