Metal Chelate Complexes of the Condensation Products of Biguanides and Salicylaldehyde : Part I. Copper Compounds

Biguanide and mono-substituted biguanides condense with salicylaldehyde to give compounds of the Schiff base type. The resultant ligands give inner-metallic complexes with transitional metals and different types of complexes are obtained under different conditions of reactions. The present communication deals with copper (II) complexes of such ligands
