Materials Data on Sm(GaPd)2 by Materials Project
Sm(PdGa)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sm is bonded in a 8-coordinate geometry to eight equivalent Pd and eight equivalent Ga atoms. All Sm–Pd bond lengths are 3.38 Å. All Sm–Ga bond lengths are 3.28 Å. Pd is bonded to four equivalent Sm and four equivalent Ga atoms to form a mixture of distorted edge, face, and corner-sharing PdSm4Ga4 tetrahedra. All Pd–Ga bond lengths are 2.53 Å. Ga is bonded in a 9-coordinate geometry to four equivalent Sm, four equivalent Pd, and one Ga atom. The Ga–Ga bond length is 2.55 Å.
