Compound <jats:bold>3</jats:bold><jats:sup>Ph</jats:sup> crystallizes from THF as THF‐adduct <jats:bold>3</jats:bold><jats:sup>Ph</jats:sup>(THF)<jats:sub>4</jats:sub> which features a straight conformation with a long Li···Li distance of 12.68(1) Å. Compound <jats:bold>3</jats:bold><jats:sup><jats:italic>t</jats:italic>Bu</jats:sup> was found to function as efficient and selective scavenger of chloride ions. In the presence of LiCl it forms anionic complexes [<jats:bold>3</jats:bold><jats:sup><jats:italic>t</jats:italic>Bu</jats:sup>Cl]<jats:sup>−</jats:sup> with a central Li‐Cl‐Li core (Li···Li = 3.75(1) Å).</jats:p>
