Poly[piperazinium(2+) [hexaaquabis(₃-benzene-1,3,5-tricarboxylato)dinickel(II)] dihydrate]

J.-Y. Han and W.-Y. Wei

Abstract: The title polymer, {(C₄H₁₂N₂)[Ni₂(C₉H₃O₆)₂(H₂O)₆]·2H₂O}_n, contains two independent Ni^II atoms, both of which are located on inversion centers. The benzene-1,3,5-tricarboxylate molecule bridges the Ni^II atoms in two coordination modes to form a one-dimensional polymeric structure. In the micropore formed by packing of the zigzag chains, there are one piperazinium(2+) cation and two water molecules.
