Synthesis and Characterization of Adenine Histidine Ternary Complexes

Abstract

Four novel mixed adenine-L-histidine ternary complexes of Cu(ll) and Ni(ll) have been synthesized in the solid state by the interaction of MCI₂.nH₂0 or M(N0₃)₂-nH₂O with adenine and L-histidine (1:1:1) in triethyl orthoformate. The complexes have been characterized by elemental and thermogravimetric analyses, magnetic measurements and infrared /electronic spectral studies. The carboxylic, the N imidazolic and amino groups of the amino acid participate in the bonding and the interaction of the metai ion with the adenine ring seems to occur through the N(9) site with additional participation of the N(6)H_2.
