COs is Tungsten Carbide structured and crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Os2- is bonded to six equivalent C2+ atoms to form a mixture of distorted corner, edge, and face-sharing OsC6 pentagonal pyramids. All Os–C bond lengths are 2.18 Å. C2+ is bonded to six equivalent Os2- atoms to form a mixture of distorted corner, edge, and face-sharing COs6 pentagonal pyramids.
COs is Molybdenum Carbide MAX Phase-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Os2- is bonded to six equivalent C2+ atoms to form a mixture of edge, face, and corner-sharing OsC6 octahedra. The corner-sharing octahedral tilt angles are 46°. All Os–C bond lengths are 2.18 Å. C2+ is bonded to six equivalent Os2- atoms to form a mixture of distorted edge and corner-sharing COs6 pentagonal pyramids.
OsC2 is Molybdenite-like structured and crystallizes in the hexagonal P-6m2 space group. The structure is two-dimensional and consists of one OsC2 sheet oriented in the (0, 0, 1) direction. Os2- is bonded to six equivalent C1+ atoms to form distorted edge-sharing OsC6 pentagonal pyramids. All Os–C bond lengths are 2.10 Å. C1+ is bonded in a 3-coordinate geometry to three equivalent Os2- atoms.
