The material structure described by Tm3Ru 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 distorted bent 150 degrees geometry to two equivalent Ru(1) atoms. In the second Tm site, Tm(2) is bonded in a 3-coordinate geometry to three equivalent Ru(1) atoms. Ru(1) is bonded in a 8-coordinate geometry to two equivalent Tm(1) and six equivalent Tm(2) atoms. is represented by the CIF card [CIF]
