Synthesis, Characterization and Antimicrobial Studies of Copper (II) Complexes of Semicarbazone and Thiosemicarbazone of m- Hydroxy Benzaldehyde and p-Hydroxy Benzaldehyde

We have synthesized Cu(II) complexes with m- hydroxy benzaldehyde semicarbazone (L1 =Hm-HBSC), m-hydroxy benzaldehyde thiosemicarbazone (L2= Hm-HBTSC), p- hydroxyl benzaldehyde semicarbazone (L3= Hp-HBSC) and p-hydroxybenzaldehyde thiosemicarbazone (L4= Hp-HBTSC). These complexes were characterized through elemental analysis, molecular weight, electrical conductance and magnetic susceptibilities at room temperature .The observed magnetic moments of all these complexes are consistent with the presence of a single unpaired electron. On the basis of above observations the complexes were proposed to be octahedral structure. These complexes were screened for anti-bacterial and antifungal properties and have exhibited potential activity.
