Abstract: The molecular structure of a donor-functionalized terphenyl-lithium compound, {(-2,2''-dimethoxy-m-terphenyl)(-Li)[-Li(tetrahydrofuran)I]}₂ or [Li₄I₂(C₄H₈O)₂(C₂₀H₁₇O₂)₂], is reported, featuring a dimeric and centrosymmetric arrangement in its solid-state structure. The molecular structure is comprised of a distorted transoid four-step ladder formed by four Li, two I, and two ipso-C atoms of the terphenyl moieties. The two methoxy functions of each terphenyl moiety coordinate to different Li atoms. One molecule of tetrahydrofuran coordinates to each of the Li atoms, which occupy terminal positions of the ladder-type arrangement.
