YOs2CP crystallizes in the orthorhombic Cmcm space group. Y(1) is bonded in a 4-coordinate geometry to four equivalent C(1) and three equivalent P(1) atoms. Os(1) is bonded in a distorted single-bond geometry to one C(1) and three equivalent P(1) atoms. C(1) is bonded to four equivalent Y(1) and two equivalent Os(1) atoms to form a mixture of corner and edge-sharing CY4Os2 octahedra. The corner-sharing octahedral tilt angles are 21°. P(1) is bonded in a 9-coordinate geometry to three equivalent Y(1) and six equivalent Os(1) atoms.
YOs2CP crystallizes in the orthorhombic Cmcm space group. Y(1) is bonded in a 4-coordinate geometry to four equivalent C(1) and three equivalent P(1) atoms. All Y(1)-C(1) bond lengths are 2.65 Å. There is one shorter (3.07 Å) and two longer (3.15 Å) Y(1)-P(1) bond lengths. Os(1) is bonded in a distorted single-bond geometry to one C(1) and three equivalent P(1) atoms. The Os(1)-C(1) bond length is 1.88 Å. There is one shorter (2.42 Å) and two longer (2.48 Å) Os(1)-P(1) bond lengths. C(1) is bonded to four equivalent Y(1) and two equivalent Os(1) atoms to form a mixture of corner and edge-sharing CY4Os2 octahedra. The corner-sharing octahedral tilt angles are 21°. P(1) is bonded in a 9-coordinate geometry to three equivalent Y(1) and six equivalent Os(1) atoms.
