SYNTHESIS AND CHARACTERIZATION OF BENZOCAINE SCHIFF BASE AND ITS COBALT COMPLEXAbstract
Ethyl4-(2-hydroxy-benzylideneamino) benzoate Schiff base (C16H15NO3), were synthesized and the structure was studied against the bases of X-ray, UV, visible, elemental analysis, 1HNMR, IR and Mass spectroscopy. The crystal structure of the nickel complex has been determined by single crystal X-ray conformed the molecule, which indicate the compound is crystalline in the monoclinic C2 / c with a = 16.0916 (5) Å, b = 6.0315 (2) Å, c =29.0072 (10) Å, α = 90.00°, β= 101.856 (2)°, γ = 90.00°, V= 2755.3 (2) Å3 and Z = 8. Because of intra-molecular hydrogen bond involving the O atom of hydroxy group and N atom of azomethine group; the two benzene rings and azomethine group are practically coplanar. The Cobalt complex was prepared; the structure was characterized in the bases of IR spectra, elemental analysis, UV – visible, and conductance measurements. Also, the biological activity of both Schiff base and its Cobalt complex show that they are biologically active.
