Abstract

Structural evidence for the Gillard mechanism of covalent hydrates is provided by two mixed-valence CuI/CuII complexes containing 2,2′-bipyridine (see picture) or 1,10-phenanthroline ligands, in which a hydroxy group is added to a carbon atom adjacent to a nitrogen atom. These complexes are synthesized by hydrothermal treatment of Cu(NO3)2, the respective N,N ligand, and terephthalic acid.
