CoIn2 is Khatyrkite-like structured and crystallizes in the monoclinic C2/c space group. Co(1) is bonded in a 10-coordinate geometry to two equivalent Co(1); four equivalent In(1); and four In(2,2) atoms. There are three inequivalent In sites. In the first In site, In(1) is bonded in a 4-coordinate geometry to four equivalent Co(1) atoms. In the second In site, In(2) is bonded in a 4-coordinate geometry to four equivalent Co(1) atoms. In the third In site, In(2) is bonded in a 4-coordinate geometry to four equivalent Co(1) atoms.
