Abstract

Three one-dimensional zinc phosphates, [C5N2H14][Zn(HPO4)(2)], I, [C10N4H26][Zn(HPO4)(2)].2H(2)O II, and [C4N2H6](2)[Zn(HPO4)], m, have been preparedemploying hydro/solvothermal methods in the presence of organic amines. While I and II consist of Linear chains of corner-shared four-membered rings,III is a polymeric wire where the amine molecule is directly bonded to themetal center. The wire, as well as the chain in these structures, are heldtogether by hydrogen bond interactions involving the amine and the framework oxygens. The polymeric zinc phosphate with wire-like architecture, m, isonly the second example of such architecture.
