Macrocyclic nickel(II), copper(II) and cobalt(II) complexes (6), (7), (9), (11), (13), (17) and (19) have been prepared from 2,2'-iminobisbenzaldehyde, the appropriate metal salt and the primary diamines 3,3'-iminobispropylamine (4), 2,2'iminobisethylamine (9, 2,2'-(iminodimethylene)bisaniline (8), azobenzene-2,2'-diamine (10), 2,2'-iminobisaniline (12), 2-amino-N-(2'-aminophenyl)benzamide (16) and 2-amino-N-(2'-aminobenzoyl)benzamide (18) respectively. The nickel(II) complex (15), zinc(11) complex (21) and copper(II) complex (22) were also prepared by similar methods. 2,2'-(Benzene- 1,2-diyldiimino)bisbenzaldehyde (25) was prepared but did not undergo metal template reactions to allow the formation of macrocyclic complexes.

4,6-Dimethoxy-3-methylindole-2,7-dicarbaldehyde (6) has been prepared by the formylation of 4,6-dimethoxy-3-methylindole (5)itself prepared by the hydride reduction of the oxoindole (4). Macrocyclic nickel(II) and copper(II) complexes (8), (10) and (12) have been prepared from the dialdehyde (6), the appropriate metal(II) acetate and the primary diamines 2,2'-iminobisaniline (7), 2-amino-N-(2'-aminophenyl)benzamide (9) and 2-amino-N-(2'-aminobenzoyl)benzamide (11) respectively.

Spectral Techniques

A string of novel coordination compounds of Cr(III) complexes have been derived and characterized from the macrocyclic ligands (L 1 -L 2 ) carried out by condensation reaction between ligands and the subsequent metal salt. The chemical composition of ligand was determined by analytical and spectral techniques i.e. elemental analysis, IR and Mass spectrocopy. Spectral techniques revealed tetradentate [N 4 ] the nature of ligand and its coordination mode to metal ion through nitrogen donor atoms. Metal complexes were characterized by elemental analyses, molar conductance, magnetic susceptibility measurements, IR, electronic spectra, ePR studies. The geometry of these complexes was ascertained by molecular modelling study by using Gaussian 09 program. All metal complexes were found to exhibit octahedral geometry around the metal ion. The newly synthesized macrocyclic ligands and metal complexes were subjected for antimicrobial screening to determine the inhibition and control against tested microorganisms, bacteria ( S.lutea , S.aureus, S.albus and E.coli ) and fungi ( A.fulviceps, U . hordei, A. niger and P.catinus ) by using disc diffusion method and agar plate technique, respectively. The experimental results suggest that metal complexes exhibit enhanced inhibition zone than free macrocyclic ligand.
