The material structure described by PrOs2SiC crystallizes in the orthorhombic Cmcm space group. Pr(1) is bonded in a 4-coordinate geometry to three equivalent Si(1) and four equivalent C(1) atoms. Os(1) is bonded in a 1-coordinate geometry to three equivalent Si(1) and one C(1) atom. Si(1) is bonded in a 9-coordinate geometry to three equivalent Pr(1) and six equivalent Os(1) atoms. C(1) is bonded to four equivalent Pr(1) and two equivalent Os(1) atoms to form a mixture of corner and edge-sharing CPr4Os2 octahedra. The corner-sharing octahedral tilt angles are 23°. is represented by the Crystallographic Information File (CIF) [CIF]
