| Abstract: | Tuning the substituents of triazoles, we obtained di- and tri-nuclearic triazole-nickel complexes [Ni2(deatrz)4(H2O)5](SO4)2 · 7H2O (1) and [Ni3(dmtrz)6(H2O)6](SO4)3 · 21H2O (2) (deatrz = 3,5-diethanyl-4-amino-1,2,4-triazole; dmtrz = 3,5-dimethanyl-1,2,4-triazole). The X-ray single-crystal diffraction results reveal that sulfate anions and water clusters form supramolecular networks in both complexes. In 1, a supramolecular two-dimensional structure was fabricated by nano-sized grid with novel tetramer water rings templated via binuclear-nickel(II) cations, while in 2, water molecules and sulfate anions construct the first sulfate-water three-dimensional supramolecular network as host to encapsulate trinuclear-nickel guests. |
