A uranium silyl compound, (Ar[tBu]N)3USi(SiMe3)3 (1; Ar = 3,5-C6H3Me2), has been synthesized, isolated, and characterized structurally and theoretically; compound 1 crystallizes in the space group P3̄ and its U−Si interatomic distance was found to be 3.091(3) Å. Geometry optimizations were carried out for the model systems H3EU(NH2)3 (E = C, Si, Ge, Sn) with a set of reasonable constraints; calculated
