The compound described by Os2C3 crystallizes in the tetragonal P-4c2 space group. There are three inequivalent Os sites. In the first Os site, Os(1) is bonded in a 6-coordinate geometry to two equivalent C(2) and four equivalent C(1) atoms. In the second Os site, Os(2) is bonded in a 8-coordinate geometry to four equivalent C(1) and four equivalent C(2) atoms. In the third Os site, Os(3) is bonded in a distorted octahedral geometry to two equivalent C(2) and four equivalent C(1) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a 4-coordinate geometry to one Os(2), one Os(3), and two equivalent Os(1) atoms. In the second C site, C(2) is bonded in a distorted pentagonal planar geometry to one Os(3), two equivalent Os(1), and two equivalent Os(2) atoms. is represented by the CIF card [CIF]
