Surprising coordination for low-valent actinides resembling uranyl(VI) in thorium(IV) organic hybrid layered and framework structures based on a graphene-like (6,3) sheet topology

Three thorium(IV)-based metal-organic hybrid compounds with 2D layered and 3D framework structures exhibiting graphene-like (6,3) sheet topologies were prepared with linkers with threefold symmetry. These compounds contain rare and relatively anisotropic coordination environments for low-valent actinides that are similar to those often observed for high-valent actinide ions.
