Materials Data on U3(SiC)2 by Materials Project
Abstract
U3Si2C2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent U+5.33+ sites. In the first U+5.33+ site, U+5.33+ is bonded in a 5-coordinate geometry to five equivalent C4- atoms. There are one shorter (2.24 Å) and four longer (2.58 Å) U–C bond lengths. In the second U+5.33+ site, U+5.33+ is bonded in a body-centered cubic geometry to eight equivalent Si4- atoms. All U–Si bond lengths are 2.94 Å. Si4- is bonded in a single-bond geometry to four equivalent U+5.33+ and one C4- atom. The Si–C bond length is 1.90 Å. C4- is bonded to five equivalent U+5.33+ and one Si4- atom to form a mixture of distorted corner and edge-sharing CU5Si octahedra. The corner-sharing octahedral tilt angles are 16°.
