Self-assembly of chelating, bridging N, N, N donor ligands and Cu(I), Cu(II), Cd(II), Hg(II): Molecular box versus coordination polymer

A series of molecular boxes and coordination polymers have been synthesized from the reaction of three chelating and bridging N, N, N donor ligands and transition metal salts. The solid state structures of all the compounds were studied by X-ray crystallography. The metal coordination geometries, coordination mode of the nitrato ligands and effects of the chlorido ligands on the structures are discussed.
