Materials Data on Y(SiPd)2 by Materials Project
Y(PdSi)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Y is bonded in a 8-coordinate geometry to eight equivalent Pd and eight equivalent Si atoms. All Y–Pd bond lengths are 3.25 Å. All Y–Si bond lengths are 3.16 Å. Pd is bonded to four equivalent Y and four equivalent Si atoms to form a mixture of distorted edge, face, and corner-sharing PdY4Si4 tetrahedra. All Pd–Si bond lengths are 2.47 Å. Si is bonded in a 9-coordinate geometry to four equivalent Y, four equivalent Pd, and one Si atom. The Si–Si bond length is 2.33 Å.
