Abstract

SmGaSb2 crystallizes in the orthorhombic C222_1 space group. The structure is three-dimensional. Sm3+ is bonded in a 8-coordinate geometry to eight Sb3- atoms. There are four shorter (3.24 Å) and four longer (3.34 Å) Sm–Sb bond lengths. Ga3+ is bonded in a bent 120 degrees geometry to two equivalent Sb3- atoms. Both Ga–Sb bond lengths are 2.77 Å. There are two inequivalent Sb3- sites. In the first Sb3- site, Sb3- is bonded in a 8-coordinate geometry to four equivalent Sm3+ and four equivalent Sb3- atoms. All Sb–Sb bond lengths are 3.08 Å. In the second Sb3- site, Sb3- is bonded to four equivalent Sm3+ and two equivalent Ga3+ atoms to form a mixture of distorted edge and corner-sharing SbSm4Ga2 pentagonal pyramids.
