The resulting ligands, L(1) and L(2) are 16- and L(3) and L(4) 17-membered pentaaza macrocycles. The complexes have been characterized by a variety of methods including IR, (1)H, (13)C NMR, DEPT, COSY(H,H), HMQC(H,C), FAB spectrometry and conductivimetry measurements. The crystal structures of CdL(2)Cl(CH(3)OH)ClO(4) (2) and CdL(4)(NO(3))(H(2)O)-ClO(4) (4) have been also determined, and it was shown that the geometry of the Cd(II) ion in the complexes is slightly distorted pentagonal pyramidal and pentagonal bipyramidal, respectively. The gas-phase structures of ligands, L(2) and L(4) and their Cd(II) complexes have also theoretically studied. (c) 2009 Published by Elsevier Ltd.
