Binuclear Metal Complexes of 1-Hydroxy-5-carboxylato-1,4-diaza-2-methyl-3-phenyl-1,-3-pentadiene with Bivalent Transition Metal Ions

Abstract

Binuclear complexes of the type [M(CAMPE)(H₂O)₂]₂ where H₂CAMPE stands for 1-hydroxy-5-carboxylato-1,4-diaza-2-methyl-3-phenyl-1,3-pentadiene and is the Schiff base derived from glycine and 1-phenyl-1,2-propanedione-2-oxime and M = CO²⁺, Ni²⁺, Cu²⁺ or Ag²⁺ have been synthesized; physical and spectroscopic analyses indicate a binuclear structure for the complexes with metal ions in an octahedral environment, where the ligand coordinates to the metal centre through azomethine nitrogen. oxime and carboxylate oxygen.
