Abstract
The cyclic (2+2) template condensation of 2,6-pyridinedicarboxaldehyde with 1,2-bis(2-aminoethoxy) ethane using Pb(SCN)2 as the metal source gave dinuclear lead(II) complex, Pb2L1(SCN)4 (1), where L1 is tetra-Schiff-base macrocycle. The transmetallation treatment of 1 with suitable metal perchlorate yield [FeL1](ClO4)2 (2) and [NiL1](ClO4)2 (3). The complexes (2 & 3) have been characterized by elemental analyses, IR, UV-visible, and ESI-MS spectroscopy. Based on spectral data, octahedral geometry may be proposed for these complexes. The electrochemical behavior of iron and nickel complexes is reported.Keywords: Macrocyclic complexes; Spectroscopic studies; 1,2-Bis(2-aminoethoxy) ethane; Charge transfer.© 2011 JSR Publications.
