Abstract

Yb6W4Al43 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. Yb is bonded in a 6-coordinate geometry to one Yb, one W, and fifteen Al atoms. The Yb–Yb bond length is 3.41 Å. The Yb–W bond length is 3.51 Å. There are a spread of Yb–Al bond distances ranging from 3.09–3.43 Å. There are two inequivalent W sites. In the first W site, W is bonded in a distorted q6 geometry to two equivalent Yb 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 (2.69 Å) and six longer (2.86 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 Yb, two W, and three equivalent Al atoms. There are one shorter (2.78 Å) and two longer (2.86 Å) Al–Al bond lengths. In the second Al site, Al is bonded in a 12-coordinate geometry to four equivalent Yb and eight Al atoms. There are a spread of Al–Al bond distances ranging from 2.77–3.09 Å.
