Hexaaquazinc(II) dichloride bis(hexamethylenetetramine) tetrahydrate

X. J. Yao, Y. W. Xuan and W. Wu

Abstract: The title compound, [Zn(H₂O)₆]Cl₂·2C₆H₁₂N₄·4H₂O, has been prepared under mild hydrothermal conditions. The Zn^II atom, located on a centre of symmetry, is coordinated by six water molecules in a distorted octahedral coordination geometry. The hexamethylenetetramine molecule is not coordinated to Zn^II but links the Zn complexes via three O-HN hydrogen bonds. The remaining N atom of the hexamethylenetetramine molecule is hydrogen-bonded to a solvent water molecule. In the crystal structure, intermolecular O-HO, O-HN and O-HCl hydrogen bonds link the components into a three-dimensional network.
