Abstract

Er6W4Al43 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. Er is bonded in a 6-coordinate geometry to one Er, one W, and fifteen Al atoms. The Er–Er bond length is 3.43 Å. The Er–W bond length is 3.48 Å. There are a spread of Er–Al bond distances ranging from 3.06–3.43 Å. There are two inequivalent W sites. In the first W site, W is bonded in a distorted q6 geometry to two equivalent Er 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 (2.68 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 Er, two W, and three equivalent Al atoms. There are one shorter (2.76 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 Er and eight Al atoms. There are a spread of Al–Al bond distances ranging from 2.74–3.06 Å.
