Abstract

A new diethyl ether adduct of uranium tetrachloride, [UCl₄(Et₂O)₂] (1), along with the previously reported mono-etherate complex [UCl₄(Et₂O)]_n (2), have been synthesized and characterized by powder X-ray diffraction, elemental analysis, and in the case of 1, single crystal X-ray diffraction. Additionally, reaction of anhydrous [UO₂(OAc)₂]_n with HCl in Et₂O/THF was found to afford the uranyl dichloride complex [UO₂Cl₂(THF)₂]₂ (3) in high purity and yield, providing an alternative and convenient entry point into anhydrous uranyl chemistry. Furthermore, comments are provided regarding the literature synthesis of [ThCl₄(dme)₂] via the reaction of [ThCl₄(H₂O)₄] with Me₃SiCl in dme, highlighting important considerations for the compound's preparation in good yield.
