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 . - 0.5H(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 triclin ic space group P1 with two molecules in a unit cell of dimensions a=0.5730( 1), b=1.0190(2), c=2.1430(4), alpha = 97.50 (1)degrees, beta = 95.33(3)degr ees, gamma = 102.85(1)degrees, V = 1. 1998 (4) nm(3), R-1 = 0.0360, wR(2) = 0.0400. The crystal contains two independent [Cu (L-Phe) (TATP) (H2O)](+) complexes Cu1 and Cu2, having essentially the same distorted square-pyramid al 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 equato rial positions and one water oxygen at an axial position.
