Ternary complex [Cu(L-tyr)(TATP)(H2O)]ClO4.H2O was synthesized and characterized by elemnetal analysis, spectroscopic and X-ray diffraction methods, where L-tyr=L-tyrosine, and TATP=1, 4, 8, 9- tetraazatriphenylene. The complex crystallizes in monoclinic space group P21, with two molecules in a unit cell of dimensions a=0.7862(2) nm, b=1.0510(5) nm, c=1.4768(3) nm, β=97.74(3)°,Z=2, V=1.2092(5) nm^3,R1=0.0341, wR2=0.0919. The central Cu(Ⅱ) ion has a distorted square-pyramidal geometry with two nitrogen atoms of TATP and the amino nitrogen and carboxylate oxygen atoms of L-tyr at the equatorial positions and one water oxygen atom at the axial position. The crystal structure shows that there are intermolecular and intramolecular aromatic-ring stacking and hydrogen bonding between the TATP-ring and the phenyl-ring of L-tyr which is similar to the base-base interactions which stabilize the double helical structure of DNA.
