文摘

An intentionally synthesized chiral terpyridyl ligand S-2(4-(2,6-di(pyridin-2-yl)pyridin-4-yl)-benzylamino)propanoic acid (H₂L) was used to construct two chiral Ni^II complexes, [Ni₂(HL)₂(N₃)(H₂O)](N₃)路19H₂O (1) and [Ni₂(HL)₂(N₃)₂]路7H₂O (2). Both complexes are dinuclear metallocyclic complexes. The monoanionic form (HL)^{鈭?/sup> of the chiral ligand coordinates to the metal centers in a bichelating antiparallel fashion to form the metallomacrocycles where the chiral metallocycles Ni₂(HL)₂ 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.}
