Rb2CoIn is Heusler structured and crystallizes in the trigonal R3m space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 7-coordinate geometry to three equivalent Co(1) and four equivalent In(1) atoms. All Rb(1)-Co(1) bond lengths are 3.63 Å. There is one shorter (3.38 Å) and three longer (4.02 Å) Rb(1)-In(1) bond lengths. In the second Rb site, Rb(2) is bonded in a 8-coordinate geometry to four equivalent Co(1) and four equivalent In(1) atoms. There is one shorter (3.38 Å) and three longer (4.02 Å) Rb(2)-Co(1) bond lengths. There is one shorter (3.38 Å) and three longer (4.02 Å) Rb(2)-In(1) bond lengths. Co(1) is bonded in a 7-coordinate geometry to three equivalent Rb(1) and four equivalent Rb(2) atoms. In(1) is bonded in a distorted body-centered cubic geometry to four equivalent Rb(1) and four equivalent Rb(2) atoms.
