Abstract The complex [Cu( L ‐Phe)(TATP)(H 2 O)]ClO 4 .0.5H 2 O 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) nm 3 , R 1 = 0.0360, wR 2 = 0.0400. The crystal contains two independent [Cu( L ‐Phe) (TATP)(H 2 O)] + 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.
