The material structure described by Tb3Ru is Cementite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 3-coordinate geometry to three equivalent Ru(1) atoms. In the second Tb site, Tb(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Ru(1) atoms. Ru(1) is bonded in a 8-coordinate geometry to two equivalent Tb(2) and six equivalent Tb(1) atoms. is represented by the CIF file [CIF]
