Macrocyclic Melamine-based ligand complexes as building blocks for the metal-directed synthesis of heterometallic di- and trinuclear compounds
Heterodi- and heterotrimetallic NiII/CuII, Ni2II/CuII and NiII/Cu2II complexes of bis- and tris-macrocyclic ligands, linked by a 1,3,5-triazine spacer group, are obtained as products of copper(II)- or nickel(II)-assisted condensations of the open-chain tetraamine complexes [M2(2,3,2-tet)]2+ [2,3,2-t...

| Zusammenfassung: | Heterodi- and heterotrimetallic NiII/CuII, Ni2II/CuII and NiII/Cu2II complexes of bis- and tris-macrocyclic ligands, linked by a 1,3,5-triazine spacer group, are obtained as products of copper(II)- or nickel(II)-assisted condensations of the open-chain tetraamine complexes [M2(2,3,2-tet)]2+ [2,3,2-tet= bis-N,N′-(2-aminoethyl)propane-1,3-diamine, M2 = NiII or CuII] with formaldehyde and the monomacrocyclic ligand complexes [M1(L1)]2+, where L1 is a cyclam-type macrocycle with a pendent melamine group (M1 = CuII or NiII). The spectroscopic (UV/Vis and EPR) and electrochemical properties of the oligonuclear heterometallic compounds in comparison with those of the homometallic analogues indicate small, but significant, intramolecular metal-metal interactions. |
