The structure described by Tm3Pt is Cementite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Tm sites. In the first Tm site, Tm(1) is bonded in a 3-coordinate geometry to three equivalent Pt(1) atoms. In the second Tm site, Tm(2) is bonded in a distorted bent 120 degrees geometry to two equivalent Pt(1) atoms. Pt(1) is bonded in a 8-coordinate geometry to two equivalent Tm(2) and six equivalent Tm(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
