The title complex 1 may be described as a pseudo‐tetrahedral anion, [LiPh 4 ] 3⊖ , surrounded by [Na(tmeda)] ⊕ counterions. The Na atoms form a nearly equilateral triangle in the middle of which is the Li atom, displaced only slightly from the Na 3 plane. Organometallic compounds of lithium and sodium were described in the 1950s by Wittig et al. However, structural characterization has been lacking so far.
