The structure described by TmRhAl crystallizes in the orthorhombic Pnma space group. Tm(1) is bonded in a 5-coordinate geometry to five equivalent Rh(1) atoms. Rh(1) is bonded in a 9-coordinate geometry to five equivalent Tm(1) and four equivalent Al(1) atoms. Al(1) is bonded to four equivalent Rh(1) atoms to form a mixture of distorted edge and corner-sharing AlRh4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
