The synthesis and X-ray crystallographic structure of a 3-D brick-wall coordination polymer of TMEDA-supported dimeric 2,3-dialkyl-1,4-dilithio-1,3-butadiene are reported. TMEDAs behave as bridging coordinating ligands rather than intramolecular chelating ligands. The Li4-tetrahedron core was stable toward the deaggregation of TMEDA because of the small steric hindrance on the butadiene skeleton.
