H3N(CH2)(6)NH3 center dot Zn-4(PO4)(2)(HPO4)(2)center dot 3H(2)O: a novel three-dimensional zinc phosphate framework containing 5- and 20-rings

The solution-mediated synthesis, single crystal structure, and some properties of H3N(CH2)(6)NH3. Zn-4(PO4)(2)(HPO4)(2). 3H(2)O, a novel organically-templated zinc phosphate containing 3-, 4-, 5-, 6- and 20-rings, are described. Vertex-linked ZnO4, PO4, and HPO4 building units self-assemble into a complex three-dimensional network incorporating extra-framework 1,6-diammoniohexane and water molecules. The organic species interacts with the framework by way of N-H . . .O hydrogen bonds. Previously unseen "trimers" of ZnO4 tetrahedra are a feature of the framework.
