Materials Data on YPOs2C by Materials Project
YOs2CP crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Y3+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent C4- atoms. All Y–C bond lengths are 2.65 Å. Os2- is bonded in a distorted single-bond geometry to one C4- and three equivalent P5+ atoms. The Os–C bond length is 1.88 Å. There are one shorter (2.42 Å) and two longer (2.48 Å) Os–P bond lengths. C4- is bonded to four equivalent Y3+ and two equivalent Os2- atoms to form a mixture of corner and edge-sharing CY4Os2 octahedra. The corner-sharing octahedral tilt angles are 21°. P5+ is bonded in a 6-coordinate geometry to six equivalent Os2- atoms.
