The aim of this report is to present the electrospray ionization mass spectrometry results of the non‐covalent interaction of two biologically active ligands, N ‐1 ‐ ( p‐ toluenesulfonyl)cytosine, 1‐TsC, 1 and N ‐1 ‐ methanesulfonylcytosine, 1‐MsC, 2 and their Cu(II) complexes Cu(1‐TsC‐ N3 ) 2 Cl 2 , 3 and Cu(1‐MsC‐ N3 ) 2 Cl 2 and 4 with biologically important cations: Na + , K + , Ca 2+ , Mg 2+ and Zn 2+ . The formation of various complex metal ions was observed. The alkali metals Na + and K + formed clusters because of electrostatic interactions. Ca 2+ and Mg 2+ salts produced the tris ligand and mixed ligand complexes. The interaction of Zn 2+ with 1–4 produced monometal and dimetal Zn 2+ complexes as a result of the affinity of Zn 2+ ions toward both O and N atoms. Copyright © 2016 John Wiley & Sons, Ltd.
