Özet

Copper(II)-Schiff base complexes have attracted extensive interest due to their structural, electronic, magnetic and luminescence properties. The title novel monomeric Cu II complex, [Cu(C10H11N2O4)(2)], has been synthesized by the reaction of 3-{[(3-hydroxypropyl) imino] methyl}-4-nitrophenol (H2L) and copper(II) acetate monohydrate in methanol, and was characterized by elemental analysis, UVand IR spectroscopies, single-crystal X-ray diffraction analysis and a photoluminescence study. The Cu II atom is located on a centre of inversion and is coordinated by two imine N atoms, two phenoxy O atoms in a mutual trans disposition and two hydroxy O atoms in axial positions, forming an elongated octahedral geometry. In the crystal, intermolecular O-H center dot center dot center dot O hydrogen bonds link the molecules to form a one-dimensional chain structure and pi-pi contacts also connect the molecules to form a three-dimensional structure. The solid-state photoluminescence properties of the complex and free H2L have been investigated at room temperature in the visible region. When the complex and H2L are excited under UV light at 349 nm, the complex displays a strong green emission at 520 nm and H2L displays a blue emission at 480 nm.
