Lu(CuAl)6 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Lu is bonded in a 12-coordinate geometry to twelve Cu and eight Al atoms. There are four shorter (3.19 Å) and eight longer (3.29 Å) Lu–Cu bond lengths. There are a spread of Lu–Al bond distances ranging from 2.95–3.08 Å. There are two inequivalent Cu sites. In the first Cu site, Cu is bonded in a 12-coordinate geometry to two equivalent Lu, four Cu, and six Al atoms. There are two shorter (2.51 Å) and two longer (2.53 Å) Cu–Cu bond lengths. There are a spread of Cu–Al bond distances ranging from 2.52–2.63 Å. In the second Cu site, Cu is bonded in a 12-coordinate geometry to two equivalent Lu, four equivalent Cu, and six Al atoms. There are a spread of Cu–Al bond distances ranging from 2.60–2.73 Å. There are three inequivalent Al sites. In the first Al site, Al is bonded in a 10-coordinate geometry to one Lu, six Cu, and three Al atoms. There are one shorter (2.63 Å) and two longer (2.83 Å) Al–Al bond lengths. In the second Al site, Al is bonded in a 8-coordinate geometry to one Lu, six Cu, and one Al atom. The Al–Al bond length is 2.64 Å. In the third Al site, Al is bonded in a 12-coordinate geometry to two equivalent Lu, six Cu, and two equivalent Al atoms.
