Materials Data on PrSiOs2C by Materials Project

PrOs2SiC crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Pr3+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent C4- atoms. All Pr–C bond lengths are 2.75 Å. Os+1.50- is bonded in a 1-coordinate geometry to three equivalent Si4+ and one C4- atom. All Os–Si bond lengths are 2.52 Å. The Os–C bond length is 1.90 Å. Si4+ is bonded in a 6-coordinate geometry to six equivalent Os+1.50- atoms. C4- is bonded to four equivalent Pr3+ and two equivalent Os+1.50- atoms to form a mixture of edge and corner-sharing CPr4Os2 octahedra. The corner-sharing octahedral tilt angles are 23°.
