The crystal structure described by PdSi crystallizes in the tetragonal I4/mcm space group. Pd(1) is bonded in a distorted pentagonal planar geometry to five equivalent Si(1) atoms. Si(1) is bonded in a 5-coordinate geometry to five equivalent Pd(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
