“…Consequently, when we observe the crystal unit perpendicularly to b (the screw axial direction), we can see parallel sheets of helixes with the same handedness, and parallel to b , alternating with antiparallely oriented sheets formed by helixes with opposite handedness (Figure ). This alternate distribution of homochiral helical sheets is rather uncommon, since alternation of enantiomers occurs typically in the three directions, − but its antiparallelism is even more uncommon. , …”

On the basis of selected reagents and reaction conditions, a chiral dinuclear trapped-valence CoII/CoIII complex was conveniently obtained {[Co2(L)(O2CCH2CO2)(H2O)]·EtOH·1.25H2O, being H3L = 2-(5-bromo-2-hydroxyphenyl)-1,3-bis[4-(5-bromo-2-hydroxyphenyl)-3-azabut-3-enyl]-1,3-imidazolidine)}. This complex behaves as a compact amphiphile, whose hydrophilic pole attracts ethanol and water solvates. Its crystal packing shows a hierarchical structure controlled by an amphiphatic nature. Molecules of each enantiomer are head-to-tail connected through intermolecular hydrogen bonds to give rise to infinite helixes. These helical chains are stacked in homochiral two-dimensional sheets with hydrophilic pockets, where water and ethanol solvates are trapped. Each layer displays its homoenantiomeric helixes with a parallel orientation, while their mirror helixes, which are alternate, are antiparallelly oriented.

The imidazole-based dicarboxylate ligand 2-(4-(pyridin-4-yl)phenyl)-1H-imidazole-4,5-dicarboxylic acid (H 3 PyPhIDC), was synthesized and its coordination chemistry was studied. Solvothermal reactions of Ca II , Mn II , Co II , and Ni II ions with H 3 PyPhIDC produced four coordination polymers, (3)], and {[Ni(μ 3 -HPyPhIDC)(H 2 O)]·H 2 O} n (4). Compounds 1-4 were analyzed by IR spectroscopy, elemental analyses, and single-crystal and powder X-ray diffraction. Compound 593(1D) infinite chain. Compounds 2 and 3 are of similar structure, showing 2D network structures with a (4,4) topology based on trinuclear clusters. Compound 4 has another type of 2D network structure with a 3-connected (4.8 2 ) topology. The results revealed that the structural diversity is attributed to the coordination numbers and geometries of metal ions as well as the coordination modes and conformations of H 3 PyPhIDC. Moreover, the thermogravimetric analyses of all the compounds as well as luminescence properties of the H 3 PyPhIDC ligand and compound 1 were also studied.
