Sumario: | In the title compound, {[Ni(C(10)H(8)N(4))(2)(H(2)O)(2)]I(2)·2C(2)H(5)OH}(n), the complex shows an octahedral environment of the Ni(2+) cation in which it is located on a centre of symmetry, linked to two water molecules and the pyridine-N atoms of four 4,4′-(diazenediyl)dipyridine ligands bridging Ni(2+) cations along the b- and c-axis directions, giving rise to a two-dimensional arrangement. The Ni—N bond lengths are in the range 2.109 (4)–2.186 (3) Å and the Ni—O bond length is 2.080 (3) Å. The 4,4′-(diazenediyl)dipyridine ligand lies on an inversion centre. An O—H⋯O hydrogen-bond interaction is observed between water and ethanol molecules. The I(−) ions can be regarded as free anions in the crystal lattice. |
