SYNTHESIS AND CARACTERIZATION OF TERNARY COMPLEXES CONTAINING Cu(II),L-HISTIDINE AND NUCLEOTIDE

The ternary complexes containing Cu(II),L-His and nucleotide(5'-GMP and 5'-IMP)were synthesized and characterized.IR and ~1H NMRspectra show that Cu(II)binds to carboxylate oxygen and imidazolenitrogen of L-His and purine N_7 of 5'-GMP and 5'-IMP.The interactionof Cu(II)with Po_3~(2-)of 5'-GMP is present,but that for 5'-IMP is notpresent.
