Solvent-controlled generation of two pairs of mononuclear single-strand helical copper(II) complexes of 2,6-pyridinediylbis(2-pyridinyl)methanone: metal-promoted hydrolysis and solvolysis with asymmetric induction

Two pairs of stable mononuclear single-strand helical complexes were obtained through controlled self-assembly using 2,6-pyridinediylbis(2-pyridinyl)methanone (L) and copper(II) salts. A mechanism of the metal-promoted hydrolysis and asymmetric solvolysis of L is proposed on the basis of the crystal structures of the complexes.
