摘要: Succinic acid or phthalic react with hydrazine hydrate and formaldehyde in the presence of metal ions to give macrocyclic complexes [ML1Cl2] [ML2Cl2][M = FeII, CoII, NiII, CuII ZnII]. The resulting cyclization has been identified, on basis i.r. 1H-n.m.r. studies. coordination amide groups through nitrogen overall geometry have assigned data obtained from elemental analyses i.r., u.v.-vis., magnetic moments, e.p.r conductivity All exhibit an octahedral geometry, except copper which is square planar, where group coordinates nitrogen, are air stable. observed low molar values suggest non-ionic nature all compounds.
