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.
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. There are a spread of Tm(1)-Pt(1) bond distances ranging from 2.82-3.31 Å. In the second Tm site, Tm(2) is bonded in a distorted bent 120 degrees geometry to two equivalent Pt(1) atoms. There is one shorter (2.75 Å) and one longer (2.83 Å) Tm(2)-Pt(1) bond length. Pt(1) is bonded in a 8-coordinate geometry to two equivalent Tm(2) and six equivalent Tm(1) atoms.
