摘要：

Complexes of a tetradentate macrocyclic ligand L with manganese(II), cobalt(II), nickel(II) and copper(II) ions have been prepared by condensation of 2,9-diamino-1,10-phenanthroline and 1,10-phenanthroline-2,9-dicarboxaldehyde in the presence of metal ion templates. Electrical conductivity measurements, ir and H-1 NMR spectral data are reported and evaluated to show that ring closure rather than polymer formation has occurred. The template condensation in the presence of chromium(III) chloride and hydrochloric acid (pH = 1) leads to the formation of the free macrocycle rather than the expected metal complex.
