Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
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 NiII complexes, [Ni2(HL)2(N3)(H2O)](N3)·19H2O (1) and [Ni2(HL)2(N3)2]·7H2O (2). Both complexes are dinuclear metallocyclic complexes. The monoanionic form (HL)− 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.
