Tetraaquadiimidazolenickel(II) naphthalene-1,5-disulfonate

P. Liu and D.-S. Deng

Abstract: The triclinic unit cell of the title compound, [Ni(C₃H₄N₂)₂(H₂O)₄](C₁₀H₆O₆S₂), contains one centrosymmetric cation and one centrosymmetric anion. In the cation, the Ni^II ion is six-coordinated by two imidazole ligands [Ni-N = 2.0568 (14) Å] and four water molecules [both independent Ni-O distances are 2.098 (1) Å] in a distorted octahedral geometry. Intermolecular O-HO and N-HO hydrogen bonds form an extensive three-dimensional network, which consolidates the crystal packing.
