Hexaaquanickel(II) dinitrate bis(hexamethylenetetramine) tetrahydrate

M.-L. Hu, M.-D. Ye and S. W. Ng

Abstract: In the title compound, [Ni(H₂O)₆](NO₃)₂·2C₆H₁₂N₄·4H₂O, the Ni atom lies on the crystallographic inversion center and is coordinated by six water molecules in an octahedral environment. The coordinated water molecules are involved in hydrogen bonding with the hexamethylenetetramine, nitrate and lattice water molecules, thus furnishing a three-dimensional network motif. The hexamethylenetetramine entity is linked to three different [Ni(H₂O)₆]²⁺ octahedra, as well as to a lattice water molecule.
