Lu3Ru is Cementite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 3-coordinate geometry to three equivalent Ru(1) atoms. In the second Lu site, Lu(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 Lu(2) and six equivalent Lu(1) atoms.
Lu3Ru is Cementite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 3-coordinate geometry to three equivalent Ru(1) atoms. There are a spread of Lu(1)-Ru(1) bond distances ranging from 2.80-3.10 Å. In the second Lu site, Lu(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Ru(1) atoms. There is one shorter (2.69 Å) and one longer (2.75 Å) Lu(2)-Ru(1) bond length. Ru(1) is bonded in a 8-coordinate geometry to two equivalent Lu(2) and six equivalent Lu(1) atoms.
