Exploring the Uranyl Organometallic Chemistry: From Single to Double Uranium−Carbon Bonds

Uranyl organometallic complexes featuring uranium(VI)−carbon single and double bonds have been obtained from uranyl UO2X2 precursors by avoiding reduction of the metal center. X-ray diffraction and density functional theory analyses of these complexes showed that the U−C and UC bonds are polarized toward the nucleophilic carbon.

以铀酰UO₂X₂为前驱体，通过避免金属中心被还原的合成方法，成功制备得到了含铀(VI)-碳单键与双键的铀酰有机金属配合物。对该类配合物开展X射线衍射（X-ray diffraction）与密度泛函理论（density functional theory）分析后发现，其U-C键与U=C键的电子云均偏向亲核性碳原子一侧。
