CoIn3 crystallizes in the orthorhombic Cmmm space group. Co(1) is bonded in a 9-coordinate geometry to one Co(1), two equivalent In(1), two equivalent In(2), and four equivalent In(3) atoms. There are three inequivalent In sites. In the first In site, In(1) is bonded in a linear geometry to two equivalent Co(1) atoms. In the second In site, In(2) is bonded in a 2-coordinate geometry to two equivalent Co(1) atoms. In the third In site, In(3) is bonded in a 4-coordinate geometry to four equivalent Co(1) atoms.
