Abstract

Hydrothermal methods were used to prepare [Cu(O₃PC₁₀H₆CO₂H)] (1) and [Cu(bpy)(HO₃PC₁₀H₆CO₂)]·2H₂O (2·2H₂O), where H₂O₃PC₁₀H₆CO₂H is 2,6-carboxynaphthalene phosphonic acid (H₃cnp). The two-dimensional structure of 1 consists of layers of edge-sharing {CuO₆} octahedra, producing an AlCl₃- type structure of fused hexagonal rings of copper octahedra, enclosing voids of hexagonal profile. The layer composition is CuO₃ or CuO₆/₂ as each oxygen bridges two copper sites. The Hcnp ligands project from either face of the copper "oxide" layer. Adjacent layers interact through hydrogen bonding interactions between the pendant -CO₂H groups of the ligand. Coordination of the bipyridine ligand in [Cu(HO₃PC₁₀H₆CO₂)] (2) obstructs expansion in two-dimensions, and the material exhibits a chain structure. The chain is constructed of binuclear units of edge-sharing '4+1' {CuO₃N₂} square pyramids linked through the dipodal {HO₃PC₁₀H₆CO₂}^2- ligands.
