Abstract

Al43Ti4Ho6 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. Ho is bonded in a 6-coordinate geometry to one Ho, one Ti, and fifteen Al atoms. The Ho–Ho bond length is 3.49 Å. The Ho–Ti bond length is 3.50 Å. There are a spread of Ho–Al bond distances ranging from 3.08–3.47 Å. There are two inequivalent Ti sites. In the first Ti site, Ti is bonded in a cuboctahedral geometry to twelve Al atoms. There are six shorter (2.70 Å) and six longer (2.87 Å) Ti–Al bond lengths. In the second Ti site, Ti is bonded in a 10-coordinate geometry to two equivalent Ho and ten Al atoms. There are a spread of Ti–Al bond distances ranging from 2.61–2.72 Å. There are seven inequivalent Al sites. In the first Al site, Al is bonded in a 12-coordinate geometry to one Ho, two Ti, and nine Al atoms. There are a spread of Al–Al bond distances ranging from 2.75–3.03 Å. In the second Al site, Al is bonded in a 12-coordinate geometry to two equivalent Ho, one Ti, and nine Al atoms.
