Materials Data on PuC2 by Materials Project
PuC2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Pu6+ is bonded in a distorted q4 geometry to ten equivalent C3- atoms. There are two shorter (2.41 Å) and eight longer (2.67 Å) Pu–C bond lengths. C3- is bonded in a 2-coordinate geometry to five equivalent Pu6+ and one C3- atom. The C–C bond length is 1.33 Å.
