The compound described by Pr2ScSi2 crystallizes in the tetragonal P4/mbm space group. Pr(1) is bonded in a 6-coordinate geometry to six 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 six equivalent Pr(1), two equivalent Sc(1), and one Si(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
