A phenyl-salicyliden-imine as a suitable ligand to build functional materials

The synthesis and characterization of 1,4-dicarboxy-phenyl-2-salicyliden-imine (DPSI), a new multi-functional and tridentate ligand, is presented together with the crystal structure of its copper(II) complex. DPSI chemical groups result very attractive because of the straightforward crystal engineering applications, so that we believe this is the first among a wide gamma of materials with promising features and properties.
