Abstract
An intentionally synthesized chiral terpyridyl ligand <i>S</i>-2(4-(2,6-di(pyridin-2-yl)pyridin-4-yl)-benzylamino)propanoic
acid
(H<sub>2</sub>L) was used to construct two chiral Ni<sup>II</sup> complexes,
[Ni<sub>2</sub>(HL)<sub>2</sub>(N<sub>3</sub>)(H<sub>2</sub>O)](N<sub>3</sub>)·19H<sub>2</sub>O (<b>1</b>) and [Ni<sub>2</sub>(HL)<sub>2</sub>(N<sub>3</sub>)<sub>2</sub>]·7H<sub>2</sub>O (<b>2</b>). Both complexes are
dinuclear metallocyclic complexes. The monoanionic form (HL)<sup>−</sup> of the chiral ligand coordinates to the metal centers in a bichelating
antiparallel fashion to form the metallomacrocycles where the chiral
metallocycles Ni<sub>2</sub>(HL)<sub>2</sub> template the formation
of a novel chiral 3D zeolite-like water framework with nanometer cages
trapping the metallocycles or anchor chiral water chains in the 1D
channels of a resulting chiral 3D supermolecule, respectively
