Materials Data on Dy(SiRh)2 by Materials Project
Dy(RhSi)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Dy is bonded in a 8-coordinate geometry to eight equivalent Rh and eight equivalent Si atoms. All Dy–Rh bond lengths are 3.22 Å. All Dy–Si bond lengths are 3.12 Å. Rh is bonded to four equivalent Dy and four equivalent Si atoms to form a mixture of distorted edge, face, and corner-sharing RhDy4Si4 tetrahedra. All Rh–Si bond lengths are 2.40 Å. Si is bonded in a 9-coordinate geometry to four equivalent Dy, four equivalent Rh, and one Si atom. The Si–Si bond length is 2.43 Å.
