The crystal structure described by OsC2 crystallizes in the hexagonal P6_3/mmc space group. Os(1) is bonded to six equivalent C(1) atoms to form distorted edge-sharing OsC6 pentagonal pyramids. C(1) is bonded in a rectangular see-saw-like geometry to three equivalent Os(1) and one C(1) atom. is represented by the CIF card [CIF]
