Programmed single step self-assembly of a [2x2] grid architecture built on metallic centers of different coordination geometries

A novel type of 2 X 2 grid type architecture incorporating two ions of different geometries results from the single step directed self-assembly of a bischelating ligand combining bridged bidentate and tridentate complexation subunits, designed so as to lead to the ion selective and toposelective introduction of two Zn(II) and two Cu(I) cations at well-defined, diagonally located positions of, respectively, octahedral and tetrahedral coordination geometry.
