Abstract

Sm2Ru5Ga9 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are four inequivalent Sm sites. In the first Sm site, Sm is bonded to two equivalent Ru and ten Ga atoms to form distorted SmGa10Ru2 cuboctahedra that share corners with four equivalent SmGa10Ru2 cuboctahedra, faces with two equivalent RuSm4Ga8 cuboctahedra, and faces with four equivalent SmGa10Ru2 cuboctahedra. Both Sm–Ru bond lengths are 3.11 Å. There are eight shorter (3.03 Å) and two longer (3.11 Å) Sm–Ga bond lengths. In the second Sm site, Sm is bonded to two equivalent Ru and ten Ga atoms to form distorted SmGa10Ru2 cuboctahedra that share corners with four equivalent SmGa10Ru2 cuboctahedra, faces with two equivalent RuSm4Ga8 cuboctahedra, and faces with four equivalent SmGa10Ru2 cuboctahedra. Both Sm–Ru bond lengths are 3.11 Å. There are eight shorter (3.03 Å) and two longer (3.11 Å) Sm–Ga bond lengths.
