Materials Data on SmPOs2C by Materials Project

SmOs2CP crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Sm3+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent C4- atoms. All Sm–C bond lengths are 2.68 Å. Os2- is bonded in a distorted single-bond geometry to one C4- and three equivalent P5+ atoms. The Os–C bond length is 1.89 Å. There are one shorter (2.43 Å) and two longer (2.50 Å) Os–P bond lengths. C4- is bonded to four equivalent Sm3+ and two equivalent Os2- atoms to form a mixture of corner and edge-sharing CSm4Os2 octahedra. The corner-sharing octahedral tilt angles are 22°. P5+ is bonded in a 6-coordinate geometry to six equivalent Os2- atoms.
