Materials Data on Th7Rh3 by Materials Project

Th7Rh3 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 Rh atoms. All Th–Rh bond lengths are 3.12 Å. In the second Th site, Th is bonded in a distorted water-like geometry to four equivalent Rh atoms. There are two shorter (2.92 Å) and two longer (3.55 Å) Th–Rh bond lengths. In the third Th site, Th is bonded in a 3-coordinate geometry to four equivalent Rh atoms. There are a spread of Th–Rh bond distances ranging from 2.87–3.62 Å. Rh is bonded in a 6-coordinate geometry to nine Th atoms.

Materials Data on ThRh3 by Materials Project

ThRh3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Th is bonded to twelve equivalent Rh atoms to form a mixture of face and corner-sharing ThRh12 cuboctahedra. All Th–Rh bond lengths are 2.93 Å. Rh is bonded in a distorted square co-planar geometry to four equivalent Th atoms.

Materials Data on ThRh2 by Materials Project

ThRh2 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Th is bonded in a 11-coordinate geometry to eleven Rh atoms. There are a spread of Th–Rh bond distances ranging from 2.74–3.12 Å. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded to five equivalent Th and six equivalent Rh atoms to form a mixture of face and corner-sharing RhTh5Rh6 trigonal bipyramids. All Rh–Rh bond lengths are 3.12 Å. In the second Rh site, Rh is bonded in a 6-coordinate geometry to six equivalent Th and eight Rh atoms. Both Rh–Rh bond lengths are 2.98 Å.
