The crystal structure described by PrCr2Si2C crystallizes in the tetragonal P4/mmm space group. Pr(1) is bonded in a distorted linear geometry to eight equivalent Si(1) and two equivalent C(1) atoms. Cr(1) is bonded in a distorted linear geometry to four equivalent Si(1) and two equivalent C(1) atoms. Si(1) is bonded in a 9-coordinate geometry to four equivalent Pr(1), four equivalent Cr(1), and one Si(1) atom. C(1) is bonded to two equivalent Pr(1) and four equivalent Cr(1) atoms to form corner-sharing CPr2Cr4 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
