The synthesis of bis(macrocyclic) complexes bearing tetraamide groups has been achieved byrntemplate condensation reaction between propylenediatnine, formaldehyde, benzidine, and succinicrnacid in the molar ratio of 4:4:1:2, respectively. The appearance of four characteristic amide bands andrntwo single sharp bands corresponding to u(N -H) of secondary of secondary amine and coordinatedrnamide groups at their appropriate positions and the absence of bands assignable to primary' amine andrnhydroxyl group in the IR spectra strongly suggest the formation of the proposed macrocylicrnframework. The assigned band positions in the electronic spectra of Co(II), Ni(II) and Cu(II) confirmrntheir octahedral geometry'. However, the low molar conductivity' values indicate their lion-electrolyticrnnature. The results of elemental analyses agree well with the proposed stoichiometry' of the bis(macrocyclic) complexes A new series of polyamide macrocyclic complexes have also been prepared by' condensation reactionrnof hydrazine hydrate and succinic acid with metal ion in 4:4:1 molar ratio, respectively'. Therndiagnostic amide bands appearing at their appropriate positions and two single bands correspondingrnto u(N-H) of coordinated amide and uncoordinated amide gr oup and non -existence of uncondensedrnbands corresponding to primary' amino and hy'droxyl groups provide enough evidence for thernformation of the proposed macrocyclic structure. Two major peaks, a broad signal in the region 8.0-rn8.8 ppm and a broad signal in the region 2.3-3.2 ppm in the H NMR spectrum of the zinc(II) complexrncorresponding to amide group protons (CO-NH, 8 H) and methylene protons of dicarboxylic moietyrn(CO- (CI Qj-CO, 16H) further conoborates the proposed macrocyclic framework . The band positionsrnhi the electronic spectra of Co(II) and Cu(II) and conductivity' data supported their final geometry'. Thernstoichiometry' has been confirmed on the basis of elemental analysis .
