Extraordinary aluminum coordination in a novel homometallic double complex salt

Journal article, 2015

We have characterized a novel aluminum-based homometallic double complex salt, incorporating discrete octa-coordinated cationic [Al(G3)(2)](3+) and hexa-coordinated anionic [Al(TfO)(4)(OH)(2)](3-) complexes (G3 = triglyme, TfO = trifluoromethanesulfonate). X-ray crystallography, Raman spectra, and DFT calculations demonstrate extraordinary weak Al3+ coordination in [Al(G3)(2)](3+).
