HELICAL GROUP 12 CO-ORDINATION - THE X-RAY CRYSTAL STRUCTURE OF A FIVE-CO-ORDINATE ZINC(II) COMPLEX

摘要

The templated diimine-containing complexes, [M(SpyNpy(2))](ClO4)(2).0.5H(2)O {where M = Zn-II, Cd-II or Hg-II}, exhibit chirality in solution (NMR) which is consistent with, and may be diagnostic of, a helical coordination array in these complexes as verified by the X-ray crystal structure of an enantiomer of the zinc(II) derivative.
