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.
