Sm(PdGa)2 crystallizes in the tetragonal I4/mmm space group. Sm(1) is bonded in a 16-coordinate geometry to eight equivalent Pd(1) and eight equivalent Ga(1) atoms. Pd(1) is bonded to four equivalent Sm(1) and four equivalent Ga(1) atoms to form a mixture of distorted edge, face, and corner-sharing PdSm4Ga4 tetrahedra. Ga(1) is bonded in a 9-coordinate geometry to four equivalent Sm(1), four equivalent Pd(1), and one Ga(1) atom.
