| 摘 要： | Reaction of [(Bu′tCp)2Er(μ-CI)]2 with Bu′Li in 1:1 molar ratio in THF at -78℃, after work-up, afforded the trimetallic erbium tetrahydride complex [Li(THF)4][{(Bu′Cp)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 (Bu′Cp)2Er units to form a triangle array connected by three bridged hydrogen atoms, and the fourth hydrogen atom coordinated to three Er^3 ions. The coordination num-ber for each Er^3 ion is 9.
