Synthesis, Spectral and Antimicrobial Studies of Some Co(II), Ni(II) and Cu(II) Complexes Containing 2-Thiophenecarboxaldehyde Moiety

Synthesis, Spectral and Antimicrobial Studies of Some Co(II), Ni(II) and Cu(II) Complexes Containing 2-Thiophenecarboxaldehyde Moiety

Some new Schiff base metal complexes of Co(II), Ni(II) and Cu(II) derived from 3-chloro-4-fluoroaniline (HL1) and 4-fluoroaniline (HL2) with 2-thiophenecarboxaldehyde have been synthesized and characterized by elemental analysis, FT-IR, FAB-mass, molar conductance, electronic spectra, ESR and magnet...
