Novel tetraiminodiphenolate (tidf2−) supramolecular assemblies containing palladium, cobalt, copper and iron(II) have been prepared and characterized by X-ray crystallography, and FTIR and UV–Vis spectroscopies. Complex 1 crystallizes as [PdCo(tidf)(H2O)2]2([Fe(CN)5NO])2·7H2O, and contains a planar macrocycle, while complex 2, [PdCu(tidf)(H2O)(ClO4)]2([Fe(CN)4(CNH)2])·2H2O, shows a slightly bent heterocyclic unit. Both structures exhibited supramolecular architectures maintained through extensive hydrogen bonding networks. Graphical Abstract: Two unique polynuclear complexes 2[PdCo(tidf)(H2O)2]([Fe(CN)5)NO])2·7H2O and 2[PdCu(tidf)(H2O)(ClO4)]([Fe(CN)4(CNH)2])·2H2O (tidf is a symmetrical tetraiminodiphenolate Robson type macrocyclic ligand) were prepared and their molecular structures and spectroscopic properties are discussed.
