The structure described by Sm2In crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 14-coordinate geometry to two equivalent Sm(1), six equivalent Sm(2), and six equivalent In(1) atoms. In the second Sm site, Sm(2) is bonded to six equivalent Sm(1) and five equivalent In(1) atoms to form a mixture of distorted face and corner-sharing SmSm6In5 trigonal bipyramids. In(1) is bonded in a 11-coordinate geometry to five equivalent Sm(2) and six equivalent Sm(1) atoms. is represented by the CIF file [CIF]
