Materials Data on Th7Fe3 by Materials Project

Th7Fe3 crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. there are three inequivalent Th sites. In the first Th site, Th is bonded in a 3-coordinate geometry to three equivalent Fe atoms. All Th–Fe bond lengths are 2.90 Å. In the second Th site, Th is bonded in a distorted water-like geometry to two equivalent Fe atoms. Both Th–Fe bond lengths are 2.75 Å. In the third Th site, Th is bonded in a 3-coordinate geometry to three equivalent Fe atoms. There are two shorter (2.75 Å) and one longer (3.02 Å) Th–Fe bond lengths. Fe is bonded in a 6-coordinate geometry to six Th atoms.
