Materials Data on Pu(SiRh)2 by Materials Project
Pu(RhSi)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Pu is bonded in a 8-coordinate geometry to eight equivalent Rh and eight equivalent Si atoms. All Pu–Rh bond lengths are 3.23 Å. All Pu–Si bond lengths are 3.08 Å. Rh is bonded to four equivalent Pu and four equivalent Si atoms to form a mixture of distorted corner, edge, and face-sharing RhPu4Si4 tetrahedra. All Rh–Si bond lengths are 2.41 Å. Si is bonded in a 9-coordinate geometry to four equivalent Pu, four equivalent Rh, and one Si atom. The Si–Si bond length is 2.38 Å.
