A template synthesis of copper(II) chelate coordination compound with 2,8-dithio-3,5,7-triazanonandithioamide-1,9 ligand has been
achieved under soft conditions at room temperature. Reaction of Cu2[Fe(CN)6] biopolymer-polypeptide matrix with aqueous-alkaline
solutions containing dithiooxamide, formaldehyde and ammonia yielded the aforesaid chelate. It has been noted that the chelate is formed
only under the given conditions and not in solution or solid phase. The molecular structure of the complex has been calculated using DFT
B3LYP technique.
Key words: self-assembly, metalheterocycle, macrotricyclic ligand, molecular structure, DFT calculation
