Synthesis, Characterization and Molecular Structure of Ternary Cu(II) Complex with 1, 4, 8, 9-Tetraazatriphenylene and L-Phenylaninate

The complex [Cu(L-Phe)(TATP)(H2O)]ClO4.0.5H2O has been synthesized and investigated by elemental analysis, molar conductivity, spectroscopic and X-ray diffraction methods, where TATP= 1,4,8,9-tetraazatriphenylene and L-phe = L-phenylaninate group. The complex crystallizes in the triclinic space group PI with two molecules in a unit cell of dimensions a=0.5730(l), b = 1.0190(2), c = 2.1430(4), α= 97.50 (1)°, β = 95.33(3)°, γ= 102.85(1)°, V= 1.1998(4) nm3, R1 = 0.0360, wR2 = 0.0400. The crystal contains two independent [Cu(L-Phe) (TATP)(H2O)]+ complexes Cu1 and Cu2, having essentially the same distorted square-pyramidal structure, where each Cu(II) ion coordinates two nitrogen atoms of TATP and the amino nitrogen and carboxylate oxygen atoms of L-Phe in the equatorial positions and one water oxygen at an axial position.
