Source of material

The schiff base ligand (2-ethoxy-6-(((quinolin-8-yl)methyl)-phenolato L was synthesized according to the literature method [1]. The synthesis of the title complex was carried out by reacting CuCl2·2H2O and the schiff base ligand (molar ratio of 1:1) in methanol under the stirring condition at room temperature. The filtrated solution was left to slowly evaporate in air to obtain single crystal suitable for X-ray diffraction with the yield about 60%.

Discussion

Due to their interesting structures and wide potential applicat tions, the schiff base complexes have all along attracted much attention, making them play an important role in the development of coordination chemistry as well as inorganic biochemistry, catalysis, optical materials and so on [2–6]. Here, we report the structure of a new copper complex based on an asymmetric tridentate schiff base ligand 2-ethoxy-6-((quinolin-8-ylimino)-methyl)phenolate. The molecular structure and the cell packing diagram of title compound, which crystallizes in monoclinic cell setting and P21/c space group, are shown in the figure. In the title compound, [Cu(L)Cl] (L=2-ethoxy-6-((quinolin-8-ylimino)methyl)phenol), the coordination sphere of the Cu ion is slightly distorted square planar, in which three positions are occupied by two N atoms and one O atom of the schiffbase ligand, and the other one results from one Cl atom. The mean deviation of the plane formed by CuN2OCl unit is 0.0435 Å, indicative of that these five atoms can form a nearly perfect plane. The Cu–O, Cu–N and Cu–Cl bond lengths are all basically consistant with those found in other Cu complexes containing similar schiff base ligands [7–8]. In the crystal structure, ππ interactions link the approximately planar molecules into stacks parallel to a axis.
