Materials Data on PuNiC2 by Materials Project
PuNiC2 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Pu6+ is bonded in a 8-coordinate geometry to eight equivalent C4- atoms. There are four shorter (2.66 Å) and four longer (2.69 Å) Pu–C bond lengths. Ni2+ is bonded in a 4-coordinate geometry to four equivalent C4- atoms. There is two shorter (1.96 Å) and two longer (1.98 Å) Ni–C bond length. C4- is bonded in a 7-coordinate geometry to four equivalent Pu6+, two equivalent Ni2+, and one C4- atom. The C–C bond length is 1.39 Å.
