摘要 Reaction of [(ButCp)2Er(μ-Cl)]2 with ButLi in 1:1 molar ratio in THF at –78℃, after work-up, afforded the trimetallic erbium tetrahydride complex [Li(THF)4][{(ButCp)2Er(μ-H)}3 (μ3-H)] (1) by [β-hydrogen elimination reaction. Crystal structure determination reveals that complex 1 has discrete ion pair structure. The anion is composed of three (ButCp)2Er units to form a triangle array connected by three bridged hydrogen atoms, and the fourth hydrogen atom coordinated to three Er3+ ions. The coordination num-ber for each Er3+ ion is 9.
