In the present study, a monomeric copper (II) co mplex has been prepared and characterized by elemental analysis, molar conductance, UV-Vis., IR and ESR spectra. The paramagnetic nature of the complex was confirmed by ESR study. The structure was unambiguously confirmed by the single crystal X-ray diffraction studies. The complex crystallizes in orthorhombic system, space group with Pbca with the values a = 17.9939 (15), b = 12.9246 (11), c = 22.2342 (13) Å and α = 90.0º, β = 90.0º and γ = 90.0º, V = 5170.87 Å 3 , Z = 8. In the X-ray structure packing is predictably influenced by strong O (5)-H (5)... O (3) and O (6)-H (6A)...O (4) hydrogen bonds.
