The synthesis and characterization with antifungal studies of the complexes of MH2L where M = Co(II), Ni(II), Cu(II) and H2L= Tetradentate macrocyclic ligand. Complexes were characterized on the basis of elemental analysis, magnetic moment, electrochemical study and conductance, Infra red with electronic spectral data. The IR studies show that the ligand has contained equatorial four mono-dentate nitrogen donor atoms. Complexes have been found to have low conductance values which indicate that the complexes act as non-electrolytic in nature. On the basis of all over the study the complexes are expected to have three-dimensional layer lattice structure involving coordination with four donor nitrogen atoms with central metal ions while the remain position of central metal ion is coordinated with halides ions in axial mode, which to give paramagnetic octahedral structure as evidenced by electronic spectral studies with magnetic moment data.
