Poly[piperazinium(2+) [hexaaquabis(μ3-benzene-1,3,5-tricarboxylato)dinickel(II)] dihydrate

Abstract

The title polymer, {(C4H12N2)[Ni2(C9H3O6)2(H2O)6]·2H2O}n, contains two independent NiII atoms, both of which are located on inversion centers. The benzene-1,3,5-tricarboxyl­ate mol­ecule bridges the NiII 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.
