Abstract

Y6Ta4Al43 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. Y is bonded in a 6-coordinate geometry to one Y, one Ta, and fifteen Al atoms. The Y–Y bond length is 3.49 Å. The Y–Ta bond length is 3.49 Å. There are a spread of Y–Al bond distances ranging from 3.07–3.48 Å. There are two inequivalent Ta sites. In the first Ta site, Ta is bonded in a cuboctahedral geometry to twelve Al atoms. There are six shorter (2.71 Å) and six longer (2.90 Å) Ta–Al bond lengths. In the second Ta site, Ta is bonded in a 10-coordinate geometry to two equivalent Y and ten Al atoms. There are a spread of Ta–Al bond distances ranging from 2.65–2.76 Å. There are seven inequivalent Al sites. In the first Al site, Al is bonded in a 12-coordinate geometry to one Y, two Ta, and nine Al atoms.
