Synthesis and characterisation of CoII, NiII and CuII complexes of a tridentate N5 macrocyclic ligand

  • 29 Accesses

  • 8 Citations

Summary

A novel tridentate macrocyclic ligand was synthesised by the reaction of 2,6-dipicolinic acid hydrazide and 2,3-butanedione. Complexes with CoII, NiII and CuII are five-coordinate trigonal bipyramidal on the basis of analyses, electrical conductance, magnetic, electronic and infrared spectral studies. I.r. studies reveal that the ligand coordinates through the pyridine nitrogen and the amido-nitrogen.
