Materials Data on U2PtC2 by Materials Project
U2PtC2 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 (2.50 Å) U–C bond lengths. Pt2- is bonded in a linear geometry to two equivalent C4- atoms. Both Pt–C bond lengths are 2.11 Å. C4- is bonded to five equivalent U5+ and one Pt2- atom to form a mixture of edge and corner-sharing CU5Pt octahedra. The corner-sharing octahedra tilt angles range from 0–11°.
