Materials Data on Th2C3 by Materials Project
Th2C3 is Plutonium carbide structured and crystallizes in the cubic I-43d space group. The structure is three-dimensional. Th4+ is bonded in a 6-coordinate geometry to nine equivalent C+2.67- atoms. There are a spread of Th–C bond distances ranging from 2.59–2.92 Å. C+2.67- is bonded to six equivalent Th4+ and one C+2.67- atom to form a mixture of distorted edge, face, and corner-sharing CTh6C trigonal bipyramids. The C–C bond length is 1.41 Å.
