Abstract

In the hydro-thermally prepared title coordination polymer, [Ni(C(2)H(6)NO(3)S)(2)(C(12)H(10)N(4))](n), the Ni(II) ion and the 1,4-bis-(1H-imidazol-1-yl)benzene ligand occupy special positions on inversion centers. The metal ion shows a slightly distorted octa-hedral coordination geometry, being linked to two N atoms of two 1,4-bis-(imidazol-1-yl)benzene ligands and to two O and two N atoms of two chelating 2-amino-ethane-sulfonate ligands. The 1,4-bis-(imidazol-1-yl)benzene ligands bridge symmetry-related Ni(II) ions forming polymeric chains along the [110] direction.
