Materials Data on Th7Co3 by Materials Project
Th7Co3 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 Co atoms. All Th–Co bond lengths are 2.94 Å. In the second Th site, Th is bonded in a distorted water-like geometry to two equivalent Co atoms. Both Th–Co bond lengths are 2.78 Å. In the third Th site, Th is bonded in a 3-coordinate geometry to three equivalent Co atoms. There are two shorter (2.79 Å) and one longer (2.93 Å) Th–Co bond lengths. Co is bonded in a 6-coordinate geometry to six Th atoms.
