Abstract:
The new Mannich base VEP (N,N’-bis-(5,5’-diethyl-barbituryl-1-methyl)-piperazine), has been synthetized by condensation
of veronal with formaldehyde and piperazine following a Mannich procedure. The new binuclear complex Cu2VEP(X)4·4H2O, X=ClO4- where VEP stands for N,N’-bis-(5,5’-diethyl-barbituryl-1-methyl)-piperazine, were obtained by metal - ligand direct
synthesis. Tetrahedral geometry of the metal ion was preserved in solution as well in solid state. The binuclear complex contain VEP in
a chair conformation.
Keywords:
copper(II) complex; Mannich base ligand; barbituric acid derivative
