A Homoleptic Cuprate(II) Complex with Deprotonated 1,6-Anhydro-[beta]-D-glucose (Levoglucosan) Ligands

The cuprate anion in the title complex, dilithium bis[1,6-anhydro-[beta]-D-glucosidato(2-)-O²,O⁴]cuprate(II) octahydrate, Li₂[Cu(C₆H₈O₅)₂].8H₂O, is a homoleptic mononuclear 1,3-polyolato(2-) complex. The ligator atoms of the levoglucosan ligand are closer together by ca 0.4 Å with respect to the uncomplexed 1,3-diol moiety of the anhydro sugar, thus exhibiting an enhanced flexibility compared with 1,2-diols.
