%X Crystalline adducts of the lithium(I) halides, LiX (X = Cl , Br, I) with N,N,N&#8242;,N&#8242;- tetramethylethyl-enediamine (tmeda) have been synthesized and characterized by single-crystal X-ray studies. Both bromide and iodide form 1 : 1 adducts which are &#956;,&#956;-dihalo-bridged binuclear species, [( tmeda )LiX2Li( tmeda )], with four-coordinate N2LiX2 lithium environments; in addition, the iodide yields an ionic 1 : 2 adduct, [Li( tmeda )2]+I-. The chloride complex is a novel 3 : 2 polymer based an a double cubane Li6Cl6 unit solvated by chelating and bridging tmeda units.
