KPu(CO3)O2 crystallizes in the hexagonal P6_3/mmc space group. K(1) is bonded to six equivalent O(1) and six equivalent O(2) atoms to form a mixture of edge and face-sharing KO12 cuboctahedra. Pu(1) is bonded in a distorted linear geometry to two equivalent O(1) atoms. C(1) is bonded in a trigonal planar geometry to three equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to three equivalent K(1) and one Pu(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent K(1) and one C(1) atom.
