Sc6Co2In crystallizes in the orthorhombic Immm space group. There are three inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a 4-coordinate geometry to one Co(1), one Co(2), one In(1), and one In(2) atom. In the second Sc site, Sc(2) is bonded in a 4-coordinate geometry to one Co(2), two equivalent Co(1), and one In(1) atom. In the third Sc site, Sc(3) is bonded in a 5-coordinate geometry to one Co(1), two equivalent Co(2), one In(1), and one In(2) atom. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to two equivalent Sc(1), two equivalent Sc(3), four equivalent Sc(2), and one Co(1) atom. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to two equivalent Sc(1), two equivalent Sc(2), four equivalent Sc(3), and one Co(2) atom. There are two inequivalent In sites. In the first In site, In(1) is bonded in a cuboctahedral geometry to four equivalent Sc(1), four equivalent Sc(2), and four equivalent Sc(3) atoms. In the second In site, In(2) is bonded in a distorted body-centered cubic geometry to four equivalent Sc(1) and four equivalent Sc(3) atoms.
