## Abstract Synthesis and characterisation of the new macrocyclic ligands L1βL4 are reported. The ligands present one or two pentaamine moieties, each containing two piperazine rings, linked by benzene or anthracene spacers. Interaction of L1 with H^+^, Cu(II), Zn(II), Hg(II), and Pd(II) and of L3
] n 1 has been synthesized and structurally characterized. Compound 1 is monoclinic, P2 1 / c with unit cell parameters a = 8.8759(9) Γ , b = 11.4112(11) Γ , c = 8.8908(9) Γ , b = 106.010(6)Β°, V = 865.6(1) Γ 3 , Z = 2 and D calc. = 1.600 g cm Γ3 . The structure refined to R 1 = 0.0245, wR 2 = 0.0626 fo
