A new mononuclear copper(II) complex, [Cu(PIBA)2(OH 2)], where PIBA is the anionic form of 2-(1-phenylimidazolidin-2-yl) benzoic acid, has been unexpectedly obtained from the reaction of 2-formylbenzoic acid, N-phenylethane-1,2-diamine, and copper perchlorate in methanol. The complex was characterized by elemental analysis, infrared spectrum, and single-cyrstal X-ray diffraction. The complex crystallizes in the triclinic space group P-1, with unit cell dimensions a = 11.812(2) A, b = 11.884(2) A, c = 22.799(3) A, α = 89.168(2)°, β = 87.290(2)°, γ = 88.604(2)°, V = 3195.5(10) A3, Z = 4, R 1 = 0.0775, and wR2 = 0.1647. The Cu atom in the complex is five-coordinated in a square pyramidal geometry by two carboxylate O and two imidazolidine N atoms from two PIBA ligands, and by one water O atom. The thermal stability of the complex has also been determined. Copyright Taylor & Francis Group, LLC.
