Abstract

The hydrothermal reaction of 4,4′-bis(1,2,4-triazol-4-yl) (btr) and benzene-1,3,5-tricarboxylic acid (H3btc) with Cd(OAc)2·2H2O at 125 °C in situ forms 4-amino-1,2,4-triazole (atr) from btr, which crystallizes to a mixed-ligand, poly-anionic chain of [Cd2(atr)22-btc)2(H2O)4]2–. Together with a hexaaquacadmium(II) cation and water molecules the anionic coordination-polymeric forms a 3-D supramolecular network of hexaaquacadmium(II)-catena-[bis(4-amino-1,2,4-triazole)tetraaquabis(benzene-1,3,5-tricarboxylato)dicadmate(II)] dihydrate, 1-D-{[Cd(H2O)6][Cd2(atr)22-btc)2(H2O)4] 2H2O}n which is based on hydrogen bonds (in part charge-assisted) and π–π interactions.
