Abstract: The title compound, Li[Co(NH₃)₆][Pu(C₃H₂O₄)₄]·5H₂O, contains isolated [Pu(C₃H₂O₄)₄]^4- complex anions. Each malonate dianion binds to the Pu atom in a bidentate fashion, resulting in the formation of six-membered metallocycles. The coordination environment of the Pu atom is a distorted square antiprism. The average Pu-O distance is 2.318 (10) Å, about 0.08 Å shorter than in analogous Th^IV complexes.
