The synthesis, structure, and spectroscopic characterization of the first transplutonium metal–organic framework (MOF) is described. The preparation and structure of Am‐GWMOF‐6, [Am2(C6H8O4)3(H2O)2][(C10H8N2)], is analogous to that of the isostructural trivalent lanthanide‐only containing material GWMOF‐6. The presented MOF architecture is used as a platform to probe Am3+ coordination chemistry and guest‐enhanced luminescent emission, whereas the framework itself provides a means to monitor the effects of self‐irradiation upon crystallinity over time. Presented here is a discussion of these properties and the opportunities that MOFs provide in the structural and spectroscopic study of actinides. The first transplutonium metal–organic framework (MOF), containing the trivalent actinide americium ([Am2(C6H8O4)3(H2O)2]⋅(C10H8N2)), is presented as Am‐GWMOF‐6, a structurally analogous compound to that of the trivalent lanthanide‐only containing material GWMOF‐6. The presented MOF architecture is used as a platform to probe Am3+ coordination chemistry and guest‐enhanced luminescent emission.
