Crystallization of anhydrous lithium(I) chloride from dry sulfolane yields a colourless crystalline 1 : 1 adduct, characterized by analysis and a single-crystal X-ray structure determination. Crystals are orthorhombic, Pna21, a 10.940(3), b 9.611(4), c 6.576(3)Ǻ, Z= 4 formula units; R was 0.033 for 869 independent 'observed' reflections. The structure is an infinite polymer containing four-coordinate (LiCl2O2) lithium, bridged by Li-Cl interactions and O,O′ sulfolanes. Li- Cl, Cl′ are 2.375(8), 2.309(7), and Li-O, O′ 2.016(7), 1.991(6)Ǻ.
