Materials Data on Gd(SiPd)2 by Materials Project

Gd(PdSi)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Gd is bonded in a 8-coordinate geometry to eight equivalent Pd and eight equivalent Si atoms. All Gd–Pd bond lengths are 3.26 Å. All Gd–Si bond lengths are 3.19 Å. Pd is bonded to four equivalent Gd and four equivalent Si atoms to form a mixture of distorted corner, edge, and face-sharing PdGd4Si4 tetrahedra. All Pd–Si bond lengths are 2.48 Å. Si is bonded in a 9-coordinate geometry to four equivalent Gd, four equivalent Pd, and one Si atom. The Si–Si bond length is 2.34 Å.
