Formation of uranium disulfide from a uranium thioamidate single-source precursor.

ABSTRACT: A single-source-precursor approach was developed to synthesize uranium-based materials outside of the typically-studied oxides. This approach allows for shorter reaction times, milder reaction conditions, and control over the chemicals present in synthesis. To this end, the first homoleptic uranium thioamidate complex was synthesized as a precursor for US₂ materials. Pyrolysis of the thioamidate results in decomposition via an alkene elimination pathway and formation of γ-US₂, which has historically been hard to access without the need for a secondary sulfur source. Despite the oxophilicity of uranium, the method successfully forms US₂ without the inclusion of oxygen in the bulk final product. These findings are supported by simultaneous thermal anal
