Abstract: The title complex, [Cu(L)], has been synthesized by the reaction of 4,4',6,6'-tetra(tert-butyl)-2,2'- [ethylenedioxybis(nitrilomethylidyne)]diphenol (H₂L) with copper(II) acetate monohydrate in ethanol and characterized by its elemental analyses, IR spectra, TG-DTA analysis and X-ray crystallography. The complex belongs to monoclinic system with space group C2/c and unit cell parameters a = 27.231(3) Å, b = 11.196(3) Å, c = 10.704(2) Å, β = 101.293(2)º, V = 3200.2(11) Å ³ and Z = 4. X-ray crystal structure of the complex reveals that Cu(II) ion lies in the N₂O₂ coordination sphere, and forms a mononuclear structure. The dihedral angle between the coordination plane of N1-Cu1-O2 and that of N1#-Cu1-O2# is 32.78(3)°, indicating that the coordination sphere has a slightly distorted tetrahedral geometry.
