Satisfactory refinement was also hampered by parameter correlations between the four independent ion pairs, and considerable disorder of two of the [Li(tmeda)2, counterions which had Cs symmetry. To prevent a non-positive-definite displacement parameter, the carbon atoms of the counterions were refined with isotropic ADP. R1, 0.088
