Materials Data on U2OsC2 by Materials Project
U2OsC2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. U5+ is bonded to five equivalent C4- atoms to form a mixture of distorted edge and corner-sharing UC5 square pyramids. There are one shorter (2.29 Å) and four longer (2.46 Å) U–C bond lengths. Os2- is bonded in a linear geometry to two equivalent C4- atoms. Both Os–C bond lengths are 2.14 Å. C4- is bonded to five equivalent U5+ and one Os2- atom to form a mixture of edge and corner-sharing CU5Os octahedra. The corner-sharing octahedra tilt angles range from 0–15°.
