The crystal structure described by SmPtAl crystallizes in the orthorhombic Pnma space group. Sm(1) is bonded in a 11-coordinate geometry to five equivalent Pt(1) and six equivalent Al(1) atoms. Pt(1) is bonded in a 9-coordinate geometry to five equivalent Sm(1) and four equivalent Al(1) atoms. Al(1) is bonded in a 4-coordinate geometry to six equivalent Sm(1) and four equivalent Pt(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
