Solution and solid-state characterization of rare silyluranium(iii) complexes

Abstract

A uranium(III) silylate complex [K(DME)₄][UI₂{(Si(SiMe₃)₂SiMe₂)₂O}] (1) was stabilized by the addition of 18-crown-6, forming [K(18-crown-6)][UI₂{(Si(SiMe₃)₂SiMe₂)₂O}] (1-crown). Crystallization under multiple conditions resulted in three distinct molecular structures. Compound 1-crown was further characterized in the solution state via¹H, ¹³C, and ²⁹Si NMR spectroscopy, and electronic absorption spectroscopy.
