摘要：
A novel series of bis(macrocyclic) binuclear complexes of the type [Co2LX2]X-2, [Ni2LX4], [CuL]X-4 and [Zn2LX4], (X = Cl or NO3) have been synthesized via the template condensation of hydrazine, 1,2-diaminoethane, formaldehyde and 1,3-dibromopropane in 1:4:4:2 molar ratio. The formation of the macrocyclic framework and the mode of bonding of the complexes have been confirmed by data obtained from elemental analyses. FT-IR, H-1 NMR, electronic spectral Studies, conductivity and magnetic susceptibility measurements. An octahedral geometry is proposed for the Ni(II) and Zn(II) complexes, while the Co(II) and Cu(II) have square-pyramidal and square-planar geometries, respectively.
