      Two new phenyl-bridged pseudopeptidic ligands have been prepared   and structurally characterised. The nature of the ligands'   substituents play an important role in the nature of the solid   state structure yielding either hydrogen bonded linked sheets of   molecules or infinite hydrogen bonded networks. Both these   ligands were reacted with a range of zinc(II)   salts with the aim of synthesising coordination polymers and   networks and exploring the role that anions could play in   determining the final structure. The crystal structures of four   of these systems (with ZnSO4 and   ZnBr2) were determined; in one case, a   3D coordination network was obtained where zinc–ligand   coordination bonds generated the 3D arrangements. Three other 3D   networks were obtained by anion-mediated hydrogen bonding of   coordination 1D chains or 2D sheets. These four very different   structures highlight the important role played by the ligands'   substituents and the counteranions present in the system.
