Abstract

Lu6W4Al43 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. Lu is bonded in a 6-coordinate geometry to one Lu, one W, and fifteen Al atoms. The Lu–Lu bond length is 3.41 Å. The Lu–W bond length is 3.47 Å. There are a spread of Lu–Al bond distances ranging from 3.05–3.42 Å. There are two inequivalent W sites. In the first W site, W is bonded in a 10-coordinate geometry to two equivalent Lu and ten Al atoms. There are a spread of W–Al bond distances ranging from 2.60–2.73 Å. In the second W site, W is bonded in a cuboctahedral geometry to twelve Al atoms. There are six shorter (2.67 Å) and six longer (2.87 Å) W–Al bond lengths. There are seven inequivalent Al sites. In the first Al site, Al is bonded in a 2-coordinate geometry to one Lu, two W, and three equivalent Al atoms. There are one shorter (2.74 Å) and two longer (2.87 Å) Al–Al bond lengths. In the second Al site, Al is bonded in a 12-coordinate geometry to four equivalent Lu and eight Al atoms. There are a spread of Al–Al bond distances ranging from 2.73–3.04 Å.
