TmPtAl crystallizes in the orthorhombic Pnma space group. Tm(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 Tm(1) and four equivalent Al(1) atoms. Al(1) is bonded to six equivalent Tm(1) and four equivalent Pt(1) atoms to form a mixture of distorted edge, corner, and face-sharing AlTm6Pt4 tetrahedra.
