title: Hexaaqua-zinc(II) dichloride bis-(hexa-methyl-enetetramine) tetra-hydrate.
abstract: The title compound, [Zn(H(2)O)(6)]Cl(2)·2C(6)H(12)N(4)·4H(2)O, has been prepared under mild hydro-thermal conditions. The Zn(II) atom, located on a centre of symmetry, is coordinated by six water mol-ecules in a distorted octa-hedral coordination geometry. The hexa-methyl-enetetra-mine mol-ecule is not coordinated to Zn(II) but links the Zn complexes via three O-H⋯N hydrogen bonds. The remaining N atom of the hexa-methyl-enetetra-mine mol-ecule is hydrogen-bonded to a solvent water mol-ecule. In the crystal structure, inter-molecular O-H⋯O, O-H⋯N and O-H⋯Cl hydrogen bonds link the components into a three-dimensional network.
