Symmetrical double lithium bridging in 2,2′-di(lithium-tmeda)biphenyl (tmeda = MeNCH2CH2NMe2): experimental confirmation of theoretical predictions
Abstract
In accordance with predictions based on molecular orbital calculations, the crystal structure of 2,2′-dilithiobiphenyl consists of monomeric units units containing a planar biphenyl unit symmetrically bridged by two tweda-complexed lithium atoms (tmeda = Me2NCH2CH2NMe2).
