Dy3(CoIn2)2 crystallizes in the hexagonal P-6 space group. Dy(1) is bonded in a 11-coordinate geometry to one Co(1), two equivalent Co(2), two equivalent In(2), and six equivalent In(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to three equivalent Dy(1) and six equivalent In(1) atoms. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to six equivalent Dy(1) and three equivalent In(1) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 10-coordinate geometry to six equivalent Dy(1), one Co(2), two equivalent Co(1), and one In(2) atom. In the second In site, In(2) is bonded in a 9-coordinate geometry to six equivalent Dy(1) and three equivalent In(1) atoms.
