Abstract: Anew ON donor ligand was synthesized by reacting ninhydrin with thiosemicarbazide. MS, NMR (1H, 13C, DEPT, HSQC, and HMBC) and UV-VIS spectra proved the formation of a new heterocyclic compound initially due to 1:1condensation between ninhydrine and thiosemicarbazide and subsequently due to hydration /tautomerization and cyclization of the thiosemicarbazone. The ligand formed a pale green Cu(II) complex in ethanoic medium.The complex was characterized by analytical, conductance, spectral (IR,UV-Vis) and magnetic susceptibility data . The data suggested the formation of a 1:2 (Cu(II) : ligand) complex with the formula [CuL2]Cl2 in which the ligand behaved as a neutral ON donor involving exocyclic carbonyl oxygen and heterocyclic ring nitrogen as coordinating centers. Square planer geometry was proposed for the complex
