The molecular crystals [Li{N(SO2CF3)2}{C6H4(OCH3)2}2] and [Li{N(SO2CF3)2}{C6F2H2(OCH3)2}2] with solid-state lithium ion conductivity have been synthesized by the addition of two equivalents of 1,2-dimethoxybenzene or 1,2-difluoro-4,5-dimethoxybenzene to Li{N(SO2CF3)2}, respectively. Single-crystal X-ray diffraction analysis revealed the formation of ionic conduction paths with an
