The compound described by PrScSi crystallizes in the tetragonal I4/mmm space group. Pr(1) is bonded in a 5-coordinate geometry to five equivalent Si(1) atoms. Sc(1) is bonded in a distorted square co-planar geometry to four equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to five equivalent Pr(1) and four equivalent Sc(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
