Unusual crystalline heterobimetallic trinuclear β-diketiminates [Yb{L(μ-Li(thf)}2] and [Yb{L′(μ-Li(thf)}2]·thf [L, L′ = {N(SiMe3)C(R)}2CH, R = Ph, C6H4Ph-4]†
Abstract
YbCl3 with successively 2KL or 2KL′ and then >2Li in thf yields crystalline [Yb{L(μ-Li(thf)}2] 1 or [Yb{L′(μ-Li(thf)}2].thf 2, characterised by X-ray, multinuclear
