The inverse podant [Li3(NBut)3S}] + stabilises a single ethylene oxide OCHCH2 anion as a high- and low-temperature polymorph of [(thf)3Li3(OCHCH2){(NBu t)3S}]

Abstract

A single ethylene oxide anion derived from the ether cleavage reaction of thf with Bu^tLi is stabilised by the inverse podant [Li₃(NBu^t)₃S}] ⁺ to give a high- and a low-temperature polymorph with a considerable difference in conformation and packing.
