Abstract
A new CuL2 (HL = α-hydroxyacetophenone) complex is synthesized and investigated by elemental analysis, IR, UV-Vis, and X-ray diffraction. The complex crystallizes in the orthorhombic space group Pbca, a = 14.595(3), b = 12.517(3), c = 15.474(3) Å, V = 2826.88(1) Å3, Z = 4. The title complex has a square-planar geometry around the central Cu2+ ion. Two molecules form a dimer via a weak Cu1…O3 interaction, and the neighboring dimers of molecules are connected into a 2D structure through two very weak C-H¡O interactions. The title complexes has high activity of killing pine wood nematodes.
